been tested for compliance within the limits of Class A computing devices, pursuant to Subpart J of Part 15, of FCC Rules, which
are designed to provide reasonable protection against such interference. Operation of this equipment in a residential area may
cause interference, in which case the user at his own expense, will be required to take whatever measures may be required to
correct the interference.

CAUTION

This product is not intended for use in the light industrial, residential or commercial environments per the instrument’s certifi­cation to EN50081-2.

Section 1: Description and Specifications

1.1 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.

Pollution Degree 2: Normally only non-conductive pollution occurs. Occasionally, however, a
temporary conductivity caused by condensation must be expected.
Altitude: for use up to 2000 meter (6562 ft.)

RFI/EMI: – EN-61326
LVD: – EN-61010-1

Input: One or two isolated sensor inputs. Measurement choices of pH/ORP, resistivity/conductivity/

TDS, % concentration, ratio conductivity, total and free chlorine, monochloramine, dissolved
oxygen, dissolved ozone, turbidity, pulse flow, temperature and raw 4-20mA input. For
contacting conductivity measurements, temperature element must be a Pt1000 RTD. For
other measurements (except ORP, flow and turbidity), use either a PT100 RTD, PT1000 RTD, or
22k NTC (D.O. only).

Outputs: Four 4-20 mA or 0-20 mA isolated current outputs. Fully scalable. Max Load: 550 Ohms.
Output 1 superimposes the HART digital signal. Outputs can be programmed for PID control.
Output dampening can be enabled with time constants from 0 to 999 seconds. HART digital
communications transmitted via current output 1 is standard on all units (option code –HT).

Alarms: Four alarm relays for process measurement(s) or temperature. Any relay can be
programmed for any measurement, timer, TPC or fault alarm operation, instead of a process
alarm. When selected, a fault alarm will activate the relay when a sensor or analyzer fault occurs.
Each relay can be configured independently. Alarm logic (high or low activation or USP*) and
deadband are user-programmable.

*USP alarm can be programmed to activate when the conductivity is within a user-selectable percentage of the limit.

1.3 Ordering Information

The Clarity II is a complete system for the determination of turbidity in water. It consists of an

nalyzer and one or two sensors with a debubbler/measuring chamber assembly and cable for each

a
sensor. A calibration cup is available as an option. Because a sensor cannot be calibrated without a
calibration cup, at least one cup must be ordered. Calibration standard (formazin or polymer
spheres) must be ordered as a separate item.

2.3 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.
