FEATURES AND APPLICATIONS

The Clarity II turbidimeter is intended for the determi-
nation of turbidity in water. Low stray light, high stabili-
ty, efficient bubble rejection, and a display resolution of
0.001 NTU make Clarity II ideal for monitoring the tur-
bidity of filtered drinking water. Because it measures
turbidity as high as 200 NTU, Clarity II is also suitable
for most raw waters. The Clarity II turbidimeter can be
used in applications other than drinking water treat-
ment. Examples are monitoring wastewater dis-
charges, 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.
SECTION 1.0.
The Clarity II turbidimeter incorporates the popular
and easy to use Solu Comp II analyzer. Menu flows
and prompts are so intuitive that a manual is practical-
ly not needed. Analog outputs are fully scalable. An
optional alarm board with three relays is also avail-
able. 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 pro-
vide a drain. To order this option, consult the factory.
A dry check is also available to periodically confirm
Clarity II operation.
