Introduction

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

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

It is designedt mounted on a wall and is designed to be connected and calibrated to various levels of pH.

This pH analyzer features fully automatic temperature compensation (Displayed on screen) and accuracy to within 0.02pH of full scale.

Control
When control of pH is required, this analyzer features a high and low relay output contact,
or 4-20mA output which can be utilised to control both alkaline and/or acid dosing control.

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

Electrode Cleaning Output
The added feature that this analyzer has, compared to others in the market is a electrode clean relay output,
which can be utilised to control a solenoid for air or water jet cleaning of the electrode surface.
(Especially useful in waste / industrial water plants)
