Drinking Water Quality Testing Instrument

Drinking water quality detectors use electrochemical and optical sensors to measure parameters such as residual chlorine, turbidity, and pH in water. They are used to monitor the quality of tap water and the output of water purification equipment, ensuring compliance with hygiene standards.
Selection
Select core indicators such as residual chlorine and TDS based on the detection parameter requirements; consider portability or online design to adapt to on-site or fixed scenarios; check the instrument calibration cycle and sensor lifespan; ensure the operation interface is simple and complies with local water quality standards.
