Introduction

Continuous online monitoring and control for any aqueous solution to accommodate a range of sensors

Description
The residual chlorine analyzer (DWA-3000A-RC) Wall mount microprocessor has been built and designed to provide
years of trouble free operation.

It is designed to be only mounted in a panel and is designed to be connected and calibrated to two types of residual chlorine electrodes.
-These are the Galvanic or Polarographic types.

This residual chlorine analyzer features fully automatic temperature compensation (Displayed on screen) and
accuracy to within 3% of full scale.

Control
When control of residual chlorine is required, this controller features a high and low relay output contact,
or 4-20mA output which can be utilised to control chlorine dosing (metering) pumps.

Alarms
When indication of alarms is required the DWA-3000A has a high / hugh alarm and a low / low alarm which can be connected to warning
lights or audible alarms to ensure an operator checks on the plant.
