Introduction

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

Description
The ORP controller (DWA-2000A-ORP) Panel 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 various levels
of ORP electrodes.

This ORP controller features accuracy to within 1mV.

Control
When control of ORP is required, this controller features a high and low relay output contact,
or 4-20mA output which can be utilised to control chlorine dosing pumps or ozone generation which utilise ORP control.

Probe Cleaning Output

The added feature that this controller has, compared to others in the market is a probe 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)

Features
*Microprocessor based Digital Program Controller
*Isolated DC (4-20/0-20/0-24 mA) Output Transmission
*Automatic Cleaning Control Function
*Low-cost For User Satisfaction
*CE Mark Accredited
