01Overview

Engineered for the field

An online ORP analyzer that tracks oxidation-reduction potential, a direct indicator of biological process conditions and the disinfecting strength of chlorinated water. It measures the potential between a platinum electrode and a reference electrode across -2000 to +2000 mV with ±1 mV accuracy, helping operators manage anoxic and aerobic zones and confirm disinfection. A double salt bridge reference resists clogging, the solid-state polymer body withstands up to 6 bar, and an anti-interference circuit with a solution grounding terminal keeps readings steady in harsh plants. The IP68 electrode mounts on an immersion bracket, with flow-through and floating-ball options, and connects to a controller such as the WQC-702.

02Key Features

What makes the WQA-020 different

01

Direct redox insight

Shows whether the process is oxidising or reducing, guiding biological treatment and disinfection.

02

Clog-resistant reference

Double salt bridge reference keeps measurement stable in wastewater.

03

Pressure-rated build

Solid-state polymer electrode handles up to 6 bar with a long service life.

04

Harsh-site ready

Anti-interference circuitry and a solution grounding terminal protect the signal.

05

Flexible mounting

Immersion bracket as standard, with flow-through and floating-ball options.
