CAUTION

This product generates, uses, and can radiate radio frequency energy and thus can cause radio communication interference.
Improper installation, or operation, may increase such interference. As temporarily permitted by regulation, this unit has not
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

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.

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.
