The HANNA HI 2300 is a bench microprocessor-based Conductivity/TDS/

NaCl/Temperature meter.

The autoranging feature of the EC and TDS ranges automatically sets the instrument to the scale with the highest possible resolution.

The conductivity measurements are manually or automatically compensated for temperature effect, with the temperature sensor inside the conductivity probe. It is also possible to disable the temperature compensation and measure the actual conductivity.

The temperature coefficient is user selectable.

The instrument is equipped with a stability indicator. With this feature the user will always know when to record a measurement.

HI 2300 includes also GLP capability and data transfer to a computer through a RS232 port.

In addition, the meter allows the user to enter an ID code to uniquely identify the instrument.

Hanna Instruments reserves the right to modify the design, construction and appearance of its products without advance notice.

BUF

%

C

• All LCD tags are displayed and a beep is generated while the instrument performs self test.

TAKING MEASUREMENTS

Immerse the probe into the solution to be tested. The sleeve holes must be completely submerged. Tap the probe repeatedly to remove any air bubbles that may be trapped inside the sleeve.

If needed, press RANGE repeatedly until the desired range (EC, TDS, NaCl) is selected on the LCD (displaying µS[mS], ppm[g/L] or %).

C

RANGE

Allow for the reading to stabilize. The upper LCD displays the measurement in the selected range, while the temperature is displayed on the lower LCD.

7

Notes:

• If the meter displays “----”, the reading is out of range.

• If the stability indicator “~” blinks, the reading is unstable.

• Make sure the meter is calibrated before taking measurements.

• If measurements are taken successively in different samples, for accurate readings it is recommended to rinse the probe thoroughly with deionized water before immersing it into the samples.

•

• TDS reading is obtained by multiplying the EC reading by the TDS factor, which has a default value of 0.50. It is possible to change the

TDS factor in the 0.40 to 0.80 range by entering setup mode and selecting the “tdS” item (see SETUP for details).

When the use of an alternate function (SETUP, TC, GLP or CALT) is requested, press and hold the ALT key first, and then the second key.

A U T O R A N G I N G

The EC and TDS scales are autoranging. The meter automatically sets the scale with the highest possible resolution.

By pressing LOCK, the autoranging feature is disabled and the current range is frozen on the LCD. “1” tag starts blinking. To restore the autoranging option press LOCK again.

LOCK

Note: Autoranging is automatically restored if the range is changed, if the setup or calibration modes are entered, or if the meter is turned off and back on again.

T E M P E R A T U R E C O M P E N S A T I O N

Three options of compensating temperature are available:

Automatic (Atc): The EC probe has a built-in temperature sensor; the temperature value is used to automatically compensate the EC/TDS reading

(from –9.9 °C to 120.0 °C), using the selected reference temperature.

Manual (Mtc): The temperature value, shown on the secondary LCD, can be manually set with the ARROW keys. The compensation is referenced at the selected reference temperature. The “°C” tag blinks when this option is active.

No Compensation (notc): The temperature value shown on the secondary LCD is not taken into account. The reading displayed on the primary LCD is the actual

EC or TDS value. The “°C” tag blinks when this option is active.

Note: The default compensation mode is ATC.

8

To select the desired option press ATC until the option is displayed on the LCD.

If temperature compensation is active, measurements are compensated using the temperature coefficient (default value

1.90 %/°C).

ATC

To change the temperature coefficient, enter the setup mode and select the “tc” item (See SETUP for details, page 14). The current temperature coefficient can be quickly viewed by pressing ALT+TC keys. The value is briefly displayed on the secondary LCD.

ALT TC

• If the temperature reading is out of –9.9 °C - 120.0 °C interval and Atc or

Mtc option is selected, the temperature limit range value will be displayed, together with the “°C” tag blinking and the instrument will do no temperature compensation.

E C / T D S C A L I B R A T I O N

EC calibration is a one-point procedure. Selectable calibration points are:

0.00 µS, 84.0 µS, 1413 µS, 5.00 mS, 12.88 mS, 80.0 mS, 111.8 mS.

To enter EC calibration, select the EC range and press CAL.

CAL

Note: TDS reading is automatically derived from the EC reading and no specific calibration for TDS is needed. Pressing CAL when TDS range is selected has no effect.

Rinse the probe with calibration solution or deionized water.

Immerse the probe into the solution. The sleeve holes must be completely submerged. Tap the probe repeatedly to remove any air bubbles that may be trapped inside the sleeve.

For zero calibration, just leave the dry probe in the air.

The “BUF” and “CAL” tags are displayed. The primary LCD displays the uncalibrated EC reading. The secondary LCD displays the buffer value. The

“~” tag blinks.

The instrument displays the “Stor Good” message and returns to measurement mode.

Notes:

• If the uncalibrated reading is too far from the expected value or the temperature value is out of 0 – 60 ºC range, calibration is not recognized.

The “CFM” tag does not appear; the “~” and “BUF” tags blink to signal wrong or contaminated calibration solution. If the temperature value is out of 0 – 60 ºC range, the “ºC” tag will also be displayed blinking on the LCD.

•

For best results choose an EC buffer value close to the sample to be measured.

• In order to minimize any EMC interferences, use plastic beakers.

• The meter uses 1.90 %/°C compensation factor during calibration. If the setup item “tc” has been set to a different value, when exiting calibration mode, the displayed value on the upper LCD might be different from the nominal buffer value.

• It is possible to set the cell constant value directly, without following the calibration procedure. To set the cell constant enter the setup mode and select “CEL” (see SETUP for details).

N a C l C A L I B R A T I O N

NaCl calibration is a one-point procedure at 100.0% NaCl. Use the

HI 7037L calibration solution (sea water solution) as a 100% NaCl standard solution.

To enter NaCl calibration select the NaCl range and press CAL.

CAL

Rinse the probe with some of the calibration solution or deionized water. Immerse the probe into HI 7037L solution. The sleeve holes must be completely submerged.

Tap the probe repeatedly to remove any air bubbles that may be trapped inside the sleeve.

TEMPERATURE CHART

The conductivity of an aqueous solution is the measure of its ability to carry an electrical current by means of ionic motion.

The conductivity invariably increases with increasing temperature.

It is affected by the type and number of ions in the solution and by the viscosity of the solution itself. Both parameters are temperature dependent. The dependency of conductivity on temperature is expressed as a relative change per

Celsius degree at a particular temperature, commonly as percent per ºC.

The following table lists the temperature dependence of the HANNA calibration buffers.

GOOD LABORATORY PRACTICE

Good Laboratory Practice (GLP) is a set of functions that allows storage and retrieval of data regarding the status of the system.

After a successful calibration, the meter automatically stores the date and time of calibration, the used calibration solution and the resulting cell constant value. All this information can be recalled by the user.

To view the last calibration data, select the desired range (EC or NaCl) and press

ALT+GLP keys.

ALT GLP

The first information appearing on the LCD is the meter “id” code.

15

By repeatedly pressing RANGE, GLP data is displayed in the following order:

Last calibration date:

RANGE

Last calibration year:

Last calibration time:

Cell constant value (K):

Offset value:

This information is displayed only if the last calibration was performed at 0.00 µS.

Calibration solution used:

BUF

If the cell constant was changed after calibration (through the “CEL” setup function), this information is not displayed.

For NaCl GLP, the last parameter is not the nominal value of the calibration solution but the actual conductivity and the temperature of the used calibration solution.

C

BUF

16

If RANGE is pressed when the last parameter is displayed, the meter returns to measurement mode.

Notes:

• To exit GLP mode at any time press ALT+GLP keys.

• If the calibration procedure was never performed, after displaying the

ID code the LCD will show the “no CAL” message blinking. Press RANGE or ALT+GLP keys to return to measurement mode.

• Last calibration data is available for EC and NaCl only. No calibration data can be recalled for TDS. If the meter is in TDS mode, by pressing

ALT+GLP keys it is possible only to view the ID code. Press ALT+GLP keys again to return to measurement mode.

• The meter has an internal lithium battery that allows to correctly update the date and time even if the power supply is disconnected.

DATA TRANSFER TO PC

Connect the meter to a PC through the RS232 output. Use HI 920010 (9 to

9-pin) connection cable.

The meter must be in measurement mode to communicate.

RANGE

The meter port is optoisolated and transmits data with a Baud rate of

2400 bps.

The user can retrieve the GLP data, request meter’s parameters and the current reading (current range only) from the PC directly. It is also possible to send a command from the PC to change ranges.

To communicate with the PC use the optional HI 92000 communication software. The software is provided with an exclusive on-line guide of all the commands available and allows data printing, plotting and exporting.

PROBE MAINTENANCE

Rinse the probe with clean water after measurements. If more cleaning is required, remove the probe sleeve and clean the probe with a cloth or a nonabrasive detergent. Make sure to reinsert the sleeve onto the probe properly and in the right direction. After cleaning the probe, recalibrate the instrument.

The platinum rings are sustained with glass. Take great care while handling the probe.
