WQM-701 Compact Multi-Parameter Water Quality Analyzer

Water Quality Monitoring

Family: WQM Series
Category: Water Quality Monitoring
Parameters: Free chlorine / ClO2, turbidity, pH, temperature, conductivity (optional)
Display: 7-inch colour touchscreen

01Overview

Engineered for the field

A compact water quality analyzer built for secondary water supply and distribution networks, measuring the key drinking water safety parameters in one wall-mounted enclosure: free chlorine or chlorine dioxide, turbidity, pH, temperature and optional conductivity. Measurement is reagent-free, the pH electrode is the only consumable, and self-cleaning turbidity and chlorine sensors extend service intervals. The turbidity channel resolves below 0.1 NTU for drinking water, while a membrane-free platinum chlorine electrode with flow stabilisation and pH and temperature compensation copes with zero chlorine, intermittent flow and low pressure. At just 30 × 40 × 18 cm, with a 7-inch touchscreen, RS485 and wireless data upload, it suits unattended pump rooms and rural water stations.

02Key Features

What makes the WQM-701 different

Five parameters, one unit

Free chlorine or ClO2, turbidity, pH, temperature and optional conductivity in a single enclosure.

Low running cost

Reagent-free measurement with the pH electrode as the only consumable.

Drinking water sensitivity

Turbidity below 0.1 NTU and compensated chlorine readings to guide disinfectant dosing.

Robust chlorine electrode

Membrane-free platinum electrode tolerates zero chlorine, intermittent flow and low pressure.

Remote supervision

RS485 and wireless data upload bring dispersed sites into one monitoring view.
