Portable Disinfectant Tester Residual Chlorine, Total Chlorine,
Chlorine Dioxide, Ozone Colorimeter
>>Principle
The disinfectant tester is widely used in food, beverage,
pharmaceutical, environmental protection, municipal water supply,
healthcare, and related industries for rapid analysis and
measurement of water quality. It is suitable for both field/on-site
rapid emergency water testing and laboratory-based water quality
analysis.
>>Application
Portable design: Flexible and convenient.
No warm-up required: Ready for immediate measurement.
Efficient & reliable: Measures one sample in just 3 minutes on average, with stable
performance.
Simple operation: Direct measurement using matched reagents and built-in
calibration curves.
User-friendly: Backlit display for easy reading and operation.
>>Feature
High-Precision Sensor: Detection limit of 0.01 μg/L, resolution of 0.01 μg/L
Rapid Response: Typically requires only 3 minutes to measure from atmospheric O₂
to μg/L-level concentrations
Simplified Calibration: Ready for measurement upon startup; no prolonged electrode
polarization needed
Extended Electrode Lifespan: Reduced replacement frequency and costs
Low-Maintenance Design: Electrode servicing interval of 4–8 months under normal use
Ultra-Low Power Consumption: Operates >1,500 hours on four AA alkaline batteries
Robust & Ergonomic: IP67 waterproof rating; magnetic attachment; lightweight (300g)
