Turbidity
TMS-E3000 Multi-Parameter Water Quality Analyzer
Multi-Parameter
Compact multi-parameter water quality analyzer for secondary water supply and distribution — simultaneous free chlorine / ClO₂, turbidity, pH, conductivity and temperature in one wall-mounted unit.
- Five key drinking water safety parameters in one compact unit
- Reagent-free electrode measurement — very low operating cost
- Purpose-built for unattended pump rooms and rural stations
- Remote data upload for centralized supervision of dispersed sites
Overview
A multi-parameter water quality analyzer combines several sensors in a single monitoring unit. At secondary supply and distribution points it continuously tracks the parameters that define drinking water safety — disinfectant residual, turbidity, pH, conductivity and temperature.
The TMS-E3000 is a multi-parameter water quality analyzer developed for monitoring rural drinking water and secondary water supply, designed in compliance with CJJ/T 271-2017 — the technical standard for online monitoring of urban water supply quality. It integrates electrode-based free chlorine / chlorine dioxide measurement with low-range turbidity, pH, conductivity and temperature sensing in a flow-through assembly, engineered for high reliability, long maintenance intervals and unattended operation in remote or decentralized locations.
Typical Applications
Features
- Low operating cost — only one consumable (pH electrode); self-cleaning turbidity and chlorine sensors reduce maintenance frequency and cost
- High accuracy — turbidity sensor designed for drinking water, capable of measuring below 0.1 NTU; chlorine measurement with flow stabilization and automatic pH / temperature compensation for disinfectant dosing guidance
- High reliability — optimized for high-turbidity rural drinking water systems; high-purity platinum chlorine electrode with no membrane or electrolyte tolerates no-chlorine, intermittent-flow and low-pressure conditions
- Compact integrated design — all parameters housed in one 30 × 40 × 18 cm enclosure, ideal for retrofits in small pump rooms or limited-space rural water stations
