CLX Online Residual Chlorine Monitor

User selectable features and innovative design sets the new CLX Online Residual Chlorine Monitor apart from the competition. Cycle times that are adjustable from 110 seconds to 10 minutes, 4-20mA and Modbus outputs that can control feed pumps and user settable alarms equates to low operating and maintenance costs. A new flow through design maintains cuvette cleanliness and allows for viewing of optical operations. The strong, shatterproof case that opens to facilitate reagent replacement also allows easy access to all service functions which reduces maintenance time. Unattended operation and low chemical usage equates to low operating cost.

Free or Total Chlorine

Can be used to measure Free or Total Chlorine - the only difference is the reagents

Low operating costs

Low reagent use translates into low operating cost of pennies a day

User selectable cycle times

Cycle times can vary between 110 seconds and 10 minutes

Colorimetric DPD chemistry

Uses inexpensive DPD chemistry rather than expensive electrodes

Simple operation

Designed for unattended operation up to 30 days

Microprocessor based technology

Ensures high quality at the industry's lowest price

Drinking water, wastewater and more

Alarms

Two user selectable alarms for sample concentration

4-20mA and RS-485 Modbus

USEPA accepted method

Made in the USA
