Features and Applications

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. Clarity
II is also suitable for applications other than drinking water treat­ment including monitoring of filtered water discharges, conden­sate returns, and clarifiers.

Both US EPA 180.1 and ISO 7027 compliant sensors are available.
US EPA 180.1 sensors use a visible light source. ISO 7027 sensors
use a near infrared LED. For regulatory monitoring in the United
States, US EPA 180.1 sensors must be used. Regulatory agencies in
other countries august have different requirements.

The Clarity II turbidimeter consists of an analyzer, with either one
or two signal input boards, sensor(s), 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 easy-to-use 56 intelli­gent analyzer. Menu screens and prompts are so intuitive on the
large LCD display that a manual is practically not needed. 4-20mA
analog outputs are fully scalable. Every unit includes four alarm
relays with interval timer functions. Alarms are fully program­mable for high/low logic and dead band. To simplify start-up and
programming, the analyzer automatically recognizes installed
turbidity signal boards and 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.

(mg/L, ppm, or no units)

Display resolution-turbidity: 4 digits; decimal point moves
from x.xxx to xxx.x

Display resolution-TSS: 4 digits; decimal point moves from
x.xxx to xxxx

Calibration methods: User-prepared standard, commercially
prepared standard, or grab sample. For total suspended solids
user must provide a linear calibration equation.

Ambient Temperature and Humidity: 0 to 55°C, (32 to 131°F);
RH 5 to 95% (non-condensing)
