Features and Applications
COMPLETE SYSTEM includes single or dual input analyzer, sensor(s), and debubbler assembly
CHOOSE U.S. EPA METHOD 180.1 or ISO METHOD 7027 compliant sensors
RANGE 0-200 NTU
RESOLUTION 0.001 NTU
FULL FEATURED ANALYZER with fully scalable analog outputs and fully programmable alarms
with interval timers
INTUITIVE, USER-FRIENDLY MENU in seven languages makes setup and calibration easy
The Clarity II turbidimeter is intended for the determination of turbidity in water. Low stray
light, high stability, efficient bubble rejection, and a display resolution of 0.001 NTU make
Clarity II ideal for monitoring the turbidity of filtered drinking water. The Clarity II turbidimeter
can be used in applications other than drinking water treatment. Examples are monitoring
wastewater discharges, condensate returns, and clarifiers.
Both USEPA 180.1 and ISO 7027-compliant sensors are available. USEPA 180.1 sensors use a
visible light source. ISO 7027 sensors use a near infrared LED. For regulatory monitoring in the
United States, USEPA 180.1 sensors must be used. Regulatory agencies in other countries may
have different requirements.
The Clarity II turbidimeter consists of an analyzer, which accepts either one or two sensors, the
sensors themselves, and a debubbler/measuring chamber and cable for each sensor. The cable
plugs into the sensor and the analyzer, making setup fast and easy. Sensors can be located as
far as 50 ft (15.2 m) away from the analyzer.
The Clarity II turbidimeter incorporates the popular and easy to use 56 analyzer. Menu flows
and prompts are so intuitive that a manual is practically not needed. Analog outputs are fully
scalable. Alarms are fully programmable for high/low logic and dead band. To simplify
programming, the analyzer automatically detects whether an EPA 180.1 or ISO 7027 sensor is
being used.
Clarity II is available in an optional configuration in which the analyzer, sensor(s), and debubbling flow cell(s) are mounted on a single back plate. The sensor cables are pre-wired to the
analyzer, so setup is exceptionally fast and easy. All the user does is mount the unit on a wall,
bring in power and sample, and provide a drain. To order this option, consult the factory.

Installation – Debubbler Assembly
See Figure 2-3 for installation.
Connect the sample line to the inlet fitting. The fitting accepts 1/4-inch OD tubing. See Section
2.6 for recommended installation of the sample port.
Attach a piece of 3/8 inch ID soft tubing to the drain fitting. The debubbler must drain to atmosphere.
NOTE:
During operation, the debubbler is under pressure. A 0.040 inch (1 mm) orifice in the
outlet provides the pressure. Back pressure helps prevent outgassing, which can lead to
bubbles accumulating on the sensor face resulting in erroneous readings. DO NOT
EXCEED 30 psig (308 kPa abs) inlet pressure.
WARNING
Before removing the sensor, be absolutely certain that the process pressure
is reduced to 0 psig and the process temperature is lowered to a safe level!
The amount of pressure in the debubbler can be estimated from the flow rate. See Table 2-1.
To control and monitor sample flow, a valved rotameter with fittings is available (PN 24103-00).
Attach the rotameter to the debubbler outlet. The rotameter can also be used to increase back
pressure on the debubbler if additional pressure is needed to prevent outgassing.

Section 3.0 Wiring
3.1
General
The T56 is easy to wire. It includes removable connectors and slide-out signal input boards. The
front panel is hinged at the bottom. The panel swings down for easy access to the wiring locations.
3.1.1.
Removable connectors and signal input boards
The T56 uses removable signal input boards and communication boards for ease of wiring and
installation. Each of the signal input boards can be partially or completely removed from the
enclosure for wiring. The T56 has three slots for placement of up to two signal input boards and
one communication board
3.1.2.
Slot 1-Left
Slot 2 – Center
Slot 3 – Right
Profi board
Signal Board 1
Signal Board 2
Signal input boards
Slots 2 and 3 are for signal input measurement boards. Wire the sensor leads to the measurement
board following the lead locations marked on the board. After wiring the sensor leads to the signal
board, carefully slide the wired board fully into the enclosure slot and take up the excess sensor
cable through the cable gland. Tighten the cable gland nut to secure the cable and ensure a sealed
enclosure.
NOTE:
For the purpose of replacing factory-installed signal input boards, Rosemount Analytical Inc. is
the sole supplier.
3.1.3.
Digital communication boards
HART digital communications is standard on the T56. A Profibus DP communication board is
available as an option for the T56 communication with a host. HART communications supports
Bell 202 digital communications over an analog 4-20mA current output. Profibus DP is an open
communications protocol which operates over a dedicated digital line to the host.
3.1.4
Alarm relays
Four alarm relays are supplied with the switching power supply (85 to 264VAC, -03 order code)
and the 24VDC power supply (20-30VDC, -02 order code). All relays can be used for process
measurement(s) or temperature. Any relay can be configured as a fault alarm instead of a process
alarm. Each relay can be configured independently and each can be programmed as an interval
timer, typically used to activate pumps or control valves. As process alarms, alarm logic (high or
low activation or USP*) and deadband are user-programmable. Customer-defined failsafe
operation is supported as a programmable menu function to allow all relays to be energized or
not-energized as a default condition upon powering the analyzer. The USP* alarm can be
programmed to activate when the conductivity is within a user-selectable percentage of the
limit. USP alarming is available only when a contacting conductivity measurement board is
installed.

Section 7.0 Calibration
7.1
Calibration – Introduction
Calibration is the process of adjusting or standardizing the analyzer to a lab test or a calibrated
laboratory instrument, or standardizing to some known reference. Completion of Quick Start
upon first power up enables live measurements but does not ensure accurate readings in the
lab or in process. Calibration should be performed with each attached sensor to ensure accurate, repeatable readings.
7.2
Turbidity
This section describes how to calibrate the turbidity sensor against a user-prepared standard as
a 2-point calibration with deionized water, against a 20 NTU user-prepared standard as a single
point calibration, and against a grab sample using a reference turbidimeter.
To calibrate the turbidity sensor, access the Calibration screen by pressing ENTER/MENU from the
main screen, select S1 or S2 Measurement and press ENTER/MENU. Press INFO at any time to learn
more about this procedure. A yellow screen will appear with detailed instructions and information.
The following calibration routine is covered:
1. Slope Calibration Slope cal with pure
water and a standard of known
turbidity
2. Standardize Calibration
Standardizing the sensor to a known
turbidity
3. Grab Calibration Standardizing the
sensor to a known turbidity based on a
reference turbidimeter
1. To calibrate the turbidity loop using Slope Calibration with pure water and a standard of
known turbidity, follow the step-by-step procedures displayed on-screen.
2. To calibrate the turbidity loop using Standardize Calibration by Standardizing the sensor to
a known turbidity, follow the step-by-step procedures displayed on-screen.
3. To calibrate the turbidity loop using Grab Calibration by Standardizing the sensor to a

7.2.1
Clarity II T56
May 2012
Slope Calibration – Turbidity
This section describes how to conduct a 2-point calibration of the turbidity sensor against a
user-prepared 20NTU standard. The calibration requires two steps. First, immerse the sensor in
filtered water having very low turbidity and measure the sensor output. Next, increase the
turbidity of the filtered water by a known amount, typically 20 NTU, and measure the sensor
output again. The analyzer takes the two measurements, applies a linearization correction (if
necessary), and calculates the sensitivity. Sensitivity is the sensor output (in mV) divided by
turbidity. A typical new sensor has a sensitivity of about 10 mV/NTU. As the sensor ages, the
sensitivity decreases. The figure below illustrates how turbidity calibration works. Before
beginning the calibration, the analyzer does a dark current measurement. Dark current is the
signal generated by the detector when no light is falling on it. The analyzer subtracts the dark
current from the raw scattered light signal and converts the result to turbidity. In highly filtered
samples, which scatter little light, the dark current can be a substantial amount of the signal
generated by the detector.
7.2.2
Standardize Calibration – Turbidity
The turbidity sensor can also be calibrated against a commercial standard. Stable 20.0 NTU
standards are available from a number of sources. Calibration using a commercial standard is
simple. Filtered deionized water is not required. Before beginning the calibration, the analyzer
does a dark current measurement. Dark current is the signal generated by the detector even
when no light is falling on it. The analyzer subtracts the dark current from the raw scattered
light signal and converts the result to turbidity. In highly filtered samples, which scatter little
light, the dark current can be a substantial amount of the signal generated by the sensor.
7.2.3
Grab Calibration – Turbidity
If desired, the turbidity sensor can be calibrated against the turbidity reading from another
instrument. The analyzer treats the value entered by the user as though it were the true
turbidity of the sample. Therefore, grab sample calibration changes the sensitivity, it does not
apply an offset to the reading.

If mineral scale is present, use a dilute acid solution applied with a cotton swab to clean away
the deposit. Rinse thoroughly with water.
Do not use abrasive cleaners or solvents.
8.2.2
Replacing the lamp/LED board
The USEPA-compliant sensor uses a tungsten filament lamp (PN 1-0901-0004-EPA) as the light
source. The lamp has an expected life of about one year. The ISO-compliant version uses an
infrared LED (PN 1-0901-0005-ISO). Its expected life is five years. The 56 analyzer continuously
monitors the source intensity and corrects for changes in source intensity caused by age. When
the source intensity becomes too low, the analyzer warns the user. The user should replace the
lamp as soon as possible.
To replace the lamp/LED board:
1. Turn off power to the analyzer.
WARNING
Explosion Hazard. Do not disconnect equipment when a flammable or combustible
atmosphere is present.
2. Remove the sensor from the measuring chamber and disconnect the cable.

Appendix
This procedure describes how to verify linearity between turbidity and TSS.
1. Collect a sample of the process liquid-you may need 10 L or more if you use the Clarity II for measuring turbidity. If
you use a laboratory turbidimeter, you will need less volume. The Clarity II requires about 500 mL for the measurement; laboratory turbidimeters require 50 mL or less. Verify that the turbidity of the sample is less than 200 NTU.
Store in a clean bottle.
2. Filter a portion of the sample to obtain at least 5 L of dilution liquid. The filtrate is needed to dilute the sample in
subsequent steps. Verify that the turbidity of the dilution water is low. If filtering the sample is impractical, use
deionized water for dilution.
3. Measure the total suspended solids (TSS) in the sample obtained in step 1. Thoroughly mix the sample before
withdrawing liquid. A magnetic stirrer is best, but inverting the sample repeatedly for about a minute works, too.
Avoid violent shaking or mixing. Refer to any standard reference work on water and wastewater testing for the
procedure for determining TSS.
4. Dilute the sample from step 1, by a factor of 0.9, 0.7, 0.5, 0.3, and 0.1. See the table for recommended volumes.
Measure TSS and turbidity for each dilution. For lower TSS values, use a larger volume of sample.

5. Plot the data obtained in step 4, with turbidity on the y-axis and TSS on the x-axis. Fit the best straight line to the
data.
6. Locate two points (P1 and P2) on the line separated as much as possible. Read the ppm and NTU value for each
point and enter these into the analyzer. See Section 6.5.2.
