IMPORTANT WARNING AND SAFETY INSTRUCTIONS
WARNING CHEMICAL BURN HAZARD: Make sure all pumps are switched off at the main circuit breakers at the house before drilling into any pipes. Securely fasten all electrical, water and chemical lines.
Locate chemical feed pumps and chemical storage tanks in a safe and secure area.
Strictly follow the acid manufacturers safety and handling protocols including hand, body and eye protection when transferring or handling acid. Safety precautions should be used when handling Muriatic acid to control pH water levels. Muriatic acid can cause serious body injury and damage pool equipment. Extra care must be taken when installing, maintaining and operating acid pump feed systems. Acid is dangerous to handle and should be properly contained, transported, poured, stored, and dispensed.
• Check the pH and sanitizer levels of the water before use.
• Periodically use an independent pH and Chlorine test kit to verify that pH and chlorine is at a safe level. If the pH and Oxidation Reduction Potential
(ORP) or Flow Cell sensors are broken, depleted or dirty with oils, lotions, or other contaminants, they can report inaccurate results to the system causing incorrect water chemistry, which could harm people or equipment.
• Check the IntelliChem main status display each day to ensure there are no Alarm messages. See “Troubleshooting” on page 46 for more information.
When using IntelliChem with a pool pump timer: The Association of Pool and Spa
Professionals (APSP) recommends that all water in a residential pool pass through the filtration system at least once every 12 hours (referred to as pool water turnover).
However, many factors have an effect on actual pump and filter system run times. Pool size, source of water, direct sun light, indoor/outdoor, screened and unscreened, filtration system, cold or hot weather, swimmer load, rain, organic debris, algae, etc., are all factors which contribute to either more or less pool pump and filter system run times. Because of these differences, it is extremely difficult to set an initial run time (starting point) for the pool pump and chlorinating system. Try initially setting the pool pump timer to 12 hours. It will take a few days to get just the right amount pool pump operating time. When the
Chlorinator is wired with a pool pump timer (see page 6) results will vary greatly from one pool installation to the next, so this should be discussed with either the pool builder or your pool professional.
Using CO2 for pH Control
Plaster pools and pools using salt-chlorine generators typically cause a slow pH rise which must be managed. With IntelliChem, muriatic acid or carbon dioxide (CO2) is dispensed into the filter system’s return water as needed until the Flow Cell pH sensor detects the proper pH level. Using CO2 for pH control eliminates the need to handle and stored acid and can be a safer method. As CO2 gas is injected into the pool water, it dissolves and creates carbonic acid. This weak acid is very efficient at lowering pH with the added benefit of self-limiting if the CO2 is over-fed.
IntelliChem™ Installation and User’s Guide

Overview
IntelliChem is a pH and ORP sensing device that dispenses correct amount of chlorine or bromine, muriatic acid or CO2 gas. IntelliChem provides continual analysis of your swimming pool water sanitation and pH levels, providing real-time status information to dispense the proper amount of muriatic acid (pH reducer) and chlorine or bromine for the correct sanitization and pH balance. IntelliChem operates with or without a salt chlorine generator to provide a self-replenishing supply of chlorine generated from salt.
IntelliChem can also connect to carbon dioxide (CO2) liquid gas tanks to lower pH in your swimming pool water. When CO2 dissolves into water it produces weak neutral bicarbonate salts which reduces pH. CO2 is environmentally friendly and produces no secondary pollution into the treated water by salts such as chlorides or sulfates. CO2 does not corrode metal equipment and does not require any special piping. IntelliChem supports Pentair Water Pool and Spa® (“Pentair”), EasyTouch®, IntelliTouch® and
SunTouch® automation control systems for pH and ORP control. IntelliChem also supports IntelliChlor® salt chlorine generator (SCG) to help manage your pool water sanitizer levels.
Operating IntelliChem
Before operating IntelliChem, it’s important to test and adjust your pool water chemistry to the recommended pool industry levels found in this manual (see page 19). If you are using an IntelliChlor salt chlorine generator, adjust the salt levels to the recommended levels in the IntelliChlor Installation and User’s Guide (P/N 520589). During normal
IntelliChem operation, no user input is required, IntelliChem will automatically sense
ORP and pH levels. The current ORP and pH levels are regularly displayed on the control panel LCD display. Use the pH Settings or ORP Settings buttons to view or adjust supply levels. The IntelliChem “Auto Setup” feature provides screen prompts for first-time setup or standard configurations such as setup reminder times, calculating feed times, proportional limits and alarms. For details, see page 6.
First Balance Your Pool Water
IMPORTANT: To help keep your pool water balanced follow these steps:
1.
Use a Test Kit (with fresh testing reagents) to measure the pH, alkalinity,
and calcium hardness of the pool water. For greater accuracy, Pentair recommends the AcuCheck3 Test Kit to measure pH, chlorine ppm, and alkalinity levels (P/N 745000110). “Balanced” water has proper levels of pH, Total Alkalinity and Calcium Hardness. This “balanced” water is neither corrosive or scaling. The pH (0-14) value is the scale of relative acidity or alkalinity. Recommended pH range is from 7.2 to 7.6. The
IntelliChem default pH value is 7.5 (see page 12).
2.
Be sure the pool chlorine level is balanced. Ideal free chlorine level should be between 1.0 - 3.0 parts per million (ppm).
3.
Use the online Langelier Saturation Index (LSI) calculator to diagnose the water balance in your pool or the IntelliChem built-in LSI calculator
(see page 24-27). Refer to: http://www.pentairpool.com/pool-owner/resources/calculators/langelier/
Note: A Saturation Index value of 0 indicates the water is chemically in balance. If the
Index is a minus (-) value, corrosive tendencies are indicated. If the Index is a plus (+)
value, scale-forming tendencies are indicated. A Saturation Index value between +0.3
to -0.3 is considered satisfactory in a swimming pool. See Saturation Index menu on page 24.

Limit (Time/Volume): Displays the current feed limit. Sets the maximum amount of time/volume in hours, minutes and seconds or volumetric units that will be allowed to feed pH chemicals. As a safety feature, the IntelliChem will only allow a certain amount of pH chemicals to feed into the system in a 24 hour period. Set the maximum amount of time in hours (0-24) that will be allowed to feed. IntelliChem tracks each dose time, and adds them together. When the maximum dose time is reached or exceeded, the ORP feed system is prevented from feeding until the next 24 hour period begins, or when the feed timers are cleared manually. The default pH Limit is based on a safe limit of 2 ppm of the size of the pool, up to a 5 oz maximum. The Limit (Time/Volume) is set by Auto Setup wizard based on pool volume and filter run time.

To protect the pool water, IntelliChem will automatically shutdown pH and ORP feed control and display an alarm message if IntelliChem (or any other dispensing device) runs non-stop for more than the selected Limit time or volume. This prevents IntelliChem from non-stop feeding pH reducer, because of a sensor error or external problem with the pool. This allows you to evaluate the pool chemistry before continuing with pH feeding.

pH Sensitivity
IntelliChem can adjust the feed times for pH depending on how close the current reading is to the set point. This helps to prevent overshooting and makes it easier for IntelliChem to reach the exact set point.
Low= (default) Full dose at 0.5 pH above setpoint
High= Full dose at 0.2 pH above setpoint
Off= Full dose at 0.005 pH above setpoint
For example: When set to LOW (full dose at 0.5 above setpoint), if pH setpoint is 7.2 and pH reading is 7.7 or above, a full dose amount is dispensed. As the pH comes closer to setpoint, say 7.45 (0.25 above setpoint - or- half the 0.5 pH value), the dispensed amount will be 1/2 of the specified dosage. And, at 0.05 (1/10th of 0.5 value) above setpoint
(7.25), the dosage will be 10% of that specified in the dosage menu. In that case, if the dosage was specified to be 10 ounces, IntelliChem will dispense only 1 ounce at a time.
This can be confusing to someone who is watching the IntelliChem because it will appear to not be dosing the full amount; therefore, in the Advanced display mode, the process timer will be shown as "%Dosing 0.1 oz", the "%" indicating that the dosage is reduced due to this Sensitivity feature.

Probe Check: No
pH Lockout: is the pH reading at which IntelliChem will no longer dose sanitizer
(Chlorine/Bromine). Above pH of 7.8 it is generally understood that the ORP reading is suppressed and therefore will not be used to administer additional sanitizer. Just bringing the pH level down will raise the available chlorine and the effective ORP. At this trip point, an alarm message will be shown on the screen and ORP doses will cease.
Range is 7.7 to 8.2, default is 7.8.
Probe Check: Enables the Open Probe Test which can determine if the pH and ORP sensor probes are disconnected or non-functional. Although it will not help determine if probes need cleaning, it will catch many types of conditions including bad wiring, disconnected cable, and open/broken probe sensor. If enabled, this feature tests the probes before starting each dose. This validates that the readings used to determine that the dose is required were accurate. If disabled, the probes should periodically be tested with the Configuration/Diagnostics/Probe Test menu item. Check all connections and replace the probes and cables if necessary.

Depending on how the IntelliChem chemical dosers are plumbed and how much water is circulating in the system where the chemicals are injected into the water stream, it may be preferred to only feed Chlorine when Acid is not feeding. This would be the pH Priority setting.
" Simultaneous allows both chemicals to feed at the same time - and can be used when both feed systems are not liquid chemicals or the injectors are separated by a safe distance in the water stream. DANGER:
Combining liquid acid and chlorine can result in the formation of hazardous and explosive gas.
" pH Priority will always feed acid first, and only during the acid mix time or general monitoring period will the IntelliChem feed the liquid chlorine sanitizer. If while feeding chlorine, the pH rises above setpoint, the ORP dose will be stopped and allow acid to feed.

This display can be used to determine if the SCG is connected and responding to the
IntelliChem. If the IntelliChlor is connected, this display may show "Please wait 2-7 minutes for ppm". This indicates the IntelliChlor is responding to initial contact but until water flow and sufficient salt level is reached, the IntelliChlor will not respond with further information like salt ppm and status. Sometimes it is helpful to cycle power on the
IntelliChlor and wait 10 minutes for the green lights before it will respond with ppm and status information; it may not respond if the Salt or Cell lights are flashing red.
If the Configuration / Hardware / ORP Control / Doser Type is set to IntelliChlor, the
IntelliChem will control the IntelliChlor as it would a doser, actively turning it on (100%) for chlorine demand, and off (0%) when the ORP reaches the desired set point.
For the Chlorinator to work when connected to an Automation controller like the

Sat Index
Saturation Index
The Saturation Index (SI), also called the Langelier Index, is a chemical equation or formula used to diagnose the water balance in the pool. The Saturation Index formula is SI = pH + TF + CF + AF - 12.1 (or 12.2 for salt pools). To calculate the
Saturation Index, you must first test the pool water for pH, temperature, calcium hardness, and total alkalinity. Refer to a chart for assigned values for your temperature, hardness, and alkalinity readings then add these to your pH value. Subtract
12.1 (or 12.2 for salt pools), which is the constant value assigned to Total Dissolved
Solids and a resultant number will be produced. A result between +/-0.3 indicates balanced water. Test results not within these values require chemical adjustments to achieve balance. This formula is more or less reliable but not guaranteed. In some cases, individual readings for pH, calcium, and Total-Alkalinity might be beyond normal recommendations, however, combined within the formula can produce “balanced water.” The SI is useful to pinpoint potential water balance problems.

pH: Chlorine produced by the IntelliChlor SCG is close to Neutral pH. However, other factors usually cause the pH of the pool water to rise. Therefore, the pH in a pool chlorinated by IntelliChlor tends to stabilize at approximately 7.8. This is within APSP standards. If the pool pH rises above 7.8, have a pool professional test to see if other factors such as high Calcium Hardness or Total Alkalinity are the cause and then balance accordingly.
Temperature: The pool water temperature can affect the saturation index value.
IntelliChem gets the temperature from the EasyTouch, IntelliTouch and SunTouch automation control system. The automation control system must have the POOL or SPA pump running to report the proper temperature to IntelliChem, otherwise IntelliChem will use its own menu's temperature value. To change the IntelliChem default temperature, select Temp and use the Up/Down arrow to adjust the temperature.
pH Level Test: Test the pH level of your pool water with a reliable test method. If necessary, adjust according to your pool professional’s recommendations. APSP’s recommended ideal range for pH is 7.2 to 7.6. Note: Never use dry acid (sodium bisulfate) to adjust pH in arid geographic areas with excessive evaporation and minimal dilution of pool water with fresh water. A buildup of by-products can damage the
IntelliChlor SCG
Calcium Hardness
Recommended range for calcium hardness is 200-500 ppm. Calcium Hardness levels should be tested weekly. Calcium hardness is the calcium carbonate scale deposited on pool surfaces. The test for Calcium Hardness is a measure of how
“hard” or “soft” the water is testing. “Hard” water can have high levels of calcium and magnesium. If these levels are too high the water becomes saturated and will leave calcium carbonate scale deposits (a “white-ish,” crystallized rough spot) on any surface inside the pool. If the levels are too low, the water becomes “soft” and will corrode surfaces inside the pool. Use TSP or Hydroquest 100 to lower Calcium
Hardness levels that are too high or add water to the pool which has a lower calcium hardness content. Levels which are too low require the addition of calcium chloride.
Total Dissolved Solids (TDS): Adding salt to pool water will raise the TDS level. While this does not adversely affect the pool water chemistry or clarity, the pool water professional testing for TDS must be made aware salt has been added to the IntelliChlor system. The individual performing the TDS test may then subtract the salinity level to arrive at a TDS level that would be compatible to a TDS reading for a non-salt water pool.
Note: If a salt chlorine generator is being used for your pool, the salt level is the TDS level of the pool.
IntelliChem™ Installation and User’s Guide

Total Alkalinity
APSP’s recommended ideal range for total alkalinity is 80 to 120 ppm for “gunite” and concrete pools and 125-170 ppm for painted, vinyl, and fiberglass pools. Test levels weekly and adjust according to your pool professional’s recommendations.
Total Alkalinity can be described as a buffer that keeps pH in order. pH depends on the ability of the total alkalinity in the water to withstand the changes in pH. If the total alkalinity is too high, adding acid (similar to pH) lowers the level. Adding a base (e.g sodium bicarbonate) when total alkalinity is low, raises the level. The level of total alkalinity in the water is a measurement of all carbonates, bicarbonates, hydroxides, and other alkaline substances found in the pool water.
Cyanuric Acid: Cyanuric acid is needed in outdoor pools to help to stabilize and maintain proper levels of chlorine. 90% of unstabilized chlorine is destroyed by the UV radiation from the sun. Cyanuric acid stabilizes chlorine in water from UV degradation.
When using the IntelliChlor SCG, the cyanuric acid level should be maintained between
30-50 ppm.
Optimum Pool Water Chemistry Conditions for Salt Water Pools
(using the IntelliChlor SCG)
In accordance with the Association of Pool and Spa Professionals (APSP) standards, it is recommended that the pool water chemistry conditions (see page 21) be maintained on an on going basis to help protect pool users, pool related equipment
and surfaces in and around the pool. These values are important to maintaining the pool equipment in proper operating condition and preventing corrosion, liming or other problems. The IntelliChlor Electronic Chlorine Generator is warranted to operate properly only if these conditions are met. For more information, refer to your local agency having jurisdiction, NSPI (National Spa and Pool Institute), the CDC (Centers for Disease
Control), or the WHO (World Health Organization). Recommended pool water chemistry is given below:
Free Chlorine: 2.0 - 4.0 ppm. Above 4.0 ppm may cause corrosion of metal components
Combined Chlorine (Chloramines): None (super chlorinate to remove all chloramines)
pH: 7.2 - 7.8 (USE MURIATIC ACID to lower pH and Soda Ash to raise pH.)
Cyanuric Acid: 30 - 50 ppm
Total Alkalinity: 80 - 120 ppm
Calcium Hardness: 200 - 400 ppm
TDS (includes salt): 3000 minium to 5700 to 6000 maximum ppm
Salt: 3000 - 4500 ppm (ideal 3400 ppm)
Metals (Copper, Iron, Manganese): None
Nitrates: None - Phosphates: Less than 125 ppb
Using the Langelier Saturation Index (LSI) to Diagnose Water
Balance
Use the Langelier Saturation Index (LSI) calculator to diagnose the water balance in your pool. Water with a LSI of 1.0 is one unit above a balanced condition. Reducing the factors by 1 unit will bring the water into equilibrium. To use the LSI calculator, refer to: http://www.pentairpool.com/pool-owner/resources/calculators/langelier/

Calculating the Saturation Index
The saturation index is a formula that relates pH, calcium and alkalinity in the pool water.
A well balanced pool water will have a formula result range between -0.3 and 0.3
Outside this range, the pool water is out of balance, potentially damaging pool equipment or scaling the salt chlorine generator. The equation to calculate Si is:
SI = pH + CHF + AF + TF - TDSF

(21.1 non-salt,
12.2 salt pools)
Cyanuric acid in the form of cyanurate ions contribute to alkalinity. Thus, a correction must be made to total alkalinity. We subtract 1/3 of the cyanuric acid level from the reading obtained in the total alkalinity test.
Total Alkalinity - 1/3 Cyanuric Acid = Corrected Alkalinity
This correction can be considerable in established pools with high cyanuric acid levels; for example, at 240 ppm cyanuric acid, the correction amounts to 80 ppm (240 ÷ 3 = 80).

General Guidelines
-
pH or ORP not able to reach setpoint
This may be a common issue that can easily be resolved by increasing the amount of chemical dispensed each day. If the pH Sensitivity is set to "Low" (the default),
IntelliChem will only administer the full dose at 0.5 from setpoint. If it seems to be stuck
0.3 from setpoint, you're only getting 3/5 of the programmed dose. Change the Sensitivity to "High" and you'll get the full dose at 0.2 pH or greater from setpoint. Or, turn pH
Sensitivity OFF - only turn it on if you're overshooting the setpoint.
Increasing the dose would essentially do the same thing. Increase the dosage as well as the dose-limit and reduce the mix time so you still get all 8 doses in the filter run time.
Diagnostics Self Test and Error codes
The overall functionality of the IntelliChem can be verified by running the self test.
Access this feature in the Configuration/Diagnostic menu. The test verify the LCD display, front panel LED indicators, push buttons, flow switch input, doser motors, relays, the RS-485 communication, and the meter.
Warning! This test will turn on the doser, so be sure that the tubing is installed in a safe manner so that the chemicals will be safely contained.

Connection between IntelliChem and the automation controller. Check RS-
485 4-wire connection, terminals, and cables.
Check that the printed circuit board is clean and dry. Dirt, condensation or water leaking into the enclosure will cause faulty readings.
Turn unit off and on again. If problem persists reload firmware or replace circuit board.
The IntelliChlor SCG device may not communicate if the water is too cold, not circulating, salt level is too low. It may also take from 2 to 10 minutes or more to begin communication.
Sometimes this can be solved by cycling power to the IntelliChlor unit and waiting again. Check cable wires and terminals for proper connection.
This indicates incompatible settings in the pH setup. Check that the hardware configuration on pH Control page 1/2 and 2/2 correspond properly. That if you specify an internal pump, you’ve chosen one of the MTR_L/R devices, and if you’ve chosen an External doser, you’ve selected an external relay. Be sure you’re not using the same output device for both pH and
ORP or an alarm output. Check dosage, and supply settings. Check that if you are dosing by volume that you have provided the GPD of the doser.
If you are unable to resolve the problem, re-run the Auto Setup Wizard.
When it prompts to use previous values be sure to choose Reset All.
This alarm will be the normal course of water chemistry control when experiencing a heavier than expected bather load, high temperature, or improperly balanced water. First check the saturation index and balance the water chemistry. Increase the dosage and filter time, increase the daily limit.
During peak loads it may be easiest to administer chemicals by hand. The
Limit can be manually cleared in the pH/ORP Settings menu, accessed by the appropriate button to the left side of the LCD display. It can also be programmed to clear automatically each time the IntelliChem powers on, or at every 24 hours of continuous run time in the pH/ORP Dosage 2/2 menu.
This is a safety feature that prevents over feeding sanitizer if the pH gets too high. As pH increases, the sanitizer becomes less effective. The proper thing to do is first reduce the pH and then see if you really need to add more sanitizer. Often bringing down the pH is sufficient to free more sanitizer which
The Open Probes Test is available in the Configuration/Diagnostics menu.
Refer to trouble shooting guide for more details. The
Configuration/Preferences menu allows you to turn on continuous probe checking. This tests the probes each time before dispensing any chemicals.
This will help ensure that the measurements used to determine the dose were not a result of invalid measurements.

This is a safety feature that prevents over feeding sanitizer if the pH gets too high. As pH increases, the sanitizer becomes less effective. The proper thing to do is first reduce the pH and then see if you really need to add more sanitizer. Often bringing down the pH is sufficient to free more sanitizer which
The Open Probes Test is available in the Configuration/Diagnostics menu.
Refer to trouble shooting guide for more details. The
Configuration/Preferences menu allows you to turn on continuous probe checking. This tests the probes each time before dispensing any chemicals.
This will help ensure that the measurements used to determine the dose were not a result of invalid measurements.

Tweaking pH
(Calibrating)
Measure the pH using a standard test kit by taking several readings and averaging the results. To Tweak the pH sensor see page 12.
Tweaking ORP
(Calibrating)
51
Always make sure the pH is at the set point before calibrating ORP.
Always control at PPM levels greater than 1.0 PPM when using
ORP sensors.
IMPORTANT: For best results the ORP should be at the ORP set point when calibrating. For best results the PPM should be at the desired level when calibrating
ORP.
To Tweak the ORP sensor see page 15.

MAINTENANCE
Winterizing: The Flow Cell sensors must be protected from freezing conditions. If the pool is winterized, plan to remove and store the sensors (as described above) as part of the normal pool winterizing process. The Flow Cell and related plumbing must be drained as well.
Water Chemistry
Always test water chemistry with a quality manual test kit. Therefore, it may be preferable to calibrate pH using commercially available reference solutions. If required, use the
IntelliChem Tweak pH feature to periodically adjust the pH reading (see above and page
12). It's important to note that changes in pH, cyanuric acid concentration, total dissolved solids, and use of additional or alternative sanitizers will all affect the primary sanitizer residual level relative to ORP. Maintain total alkalinity on regular basis to ensure pH stability. To maintain a consistent sanitizer residual in parts per million (ppm), periodically adjust the ORP level.
Sensor Maintenance: The Flow Cell sensors must be clean and free from oil, chemical deposits and contamination to function properly. After saturation in pool or spa water, the sensors may need to be cleaned on a weekly or monthly basis depending on bather load and other pool specific characteristics. Slow response, increased need to calibrate pH, and inconsistent readings are indications that the probes are in need of cleaning.

MAINTENANCE
(Continued)
Cleaning the Flow Cell Sensors: To clean the ORP and pH sensors, turn off the AC source power to IntelliChem at the GFCI switch. Disconnect the probe connectors from the Flow Cell, unscrew the probe and carefully remove them from the Flow Cell. Clean the reference junction (the white ring at the bottom of the probe body) with a soft toothbrush. A household liquid dish washing detergent may also be used to remove any oil. Rinse with fresh water and reinstall probes. If properly cleaned probes continue to provide unstable readings or require excessive calibration, the probes should be replaced. Probe exposed to atmospheric conditions will cause the probe tips to dry out.
Store the sensors with the included plastic sensors storage caps if removed from the
Flow Cell for more than one hour. If the storage caps have been misplaced, store the probes individually in small glass or plastic containers with clean water covering the sensor tips. Store sensors in a location that will not be subjected to freezing temperatures.
Sensor Care
Contamination of the sensing elements often results in slow response and inaccurate readings. Clean the elements by the following procedures:
pH and ORP Sensors
1. Wash electrode tip in a liquid detergent and water. Carefully use a soft bristled toothbrush to wash the electrode tip and white sensing ring.
2.
Rinse after cleaning. To reinstall the flow cell (see page 33). Hand tighten to sensors to secure in place.
3.
Make sure the O-ring is installed on sensor.
4.
If the cable is longer than needed, it should be coiled neatly and attached under the enclosure.
pH Sensors Only
5.
Attempt to clean the sensor with liquid detergent first.
6.
If this is not successful, swirl the tip of the sensor in a 5 parts water and 1 part muriatic acid solution for 10 - 20 seconds.
7.
Rinse again and reinstall.
WARNING Do not rub hard the glass element in the sensor or use sand paper or other polishing material to clean. HANDLE ELECTRODE CAREFULLY Sensors contain external and internal glass elements. Do not drop or otherwise subject the sensor to vibration, physical impact, or freezing conditions. ANY TYPE OF BREAKAGE IS
NOT COVERED UNDER WARRANTY.
pH and ORP Sensors: pH electrodes sense the acidity of the water and work with any acid or base. The blue bands on the cables identify the pH sensors. The red bands on the cables identify ORP sensors. Each sensor is also identified on the sensor body. ORP electrodes are used to monitor the Oxidation Reduction Potential
(ORP is sanitization quality of the water) of a given solution. The sensing element of the ORP electrode is made of a precious metal such as platinum or gold.
Sensors: IntelliChem measures the following sensor measurements with the listed characteristics:
pH Range:
ORP Range:
4.00 to 9.99
0 to 999 mV
Flow Switch: This input measures if a switch is open or closed. Open is no water flow.
A closed switch indicates flow.

Frequently asked questions
The recommended pH range for a swimming pool is between 7.2 and 7.6. This ensures that the water is neither corrosive nor scaling.
ORP stands for Oxidation Reduction Potential. It measures the sanitization quality of the water, indicating how effectively chlorine or bromine is working to kill bacteria and algae.
CO2 is environmentally friendly and produces no secondary pollution into the treated water by salts such as chlorides or sulfates. It also does not corrode metal equipment and does not require any special piping.
To adjust the pH set point, press the MENU button, then navigate to the 'pH Menu' and select the 'pH Set Point' option. You can then use the left/right arrow buttons to increase or decrease the pH set point value.
You can use a test kit to measure the pH, alkalinity, and calcium hardness of the pool water. You can then use the Langelier Saturation Index (LSI) calculator to diagnose the water balance in your pool, or use the IntelliChem's built-in LSI calculator.
