The HQ-3200 (PO4) phosphate water quality automatic analyzer uses the national standard ammonium molybdate spectrophotometric method to monitor phosphate parameters in water online. Its unique reaction system design ensures that the instrument can measure quickly and accurately. It can be widely used for key monitoring of various water qualities such as seawater, river water, drinking water sources, and industrial wastewater.
Product Features
1. Automatic turbidity and chromaticity compensation function, suitable for high turbidity water bodies;
2. Equipped with an efficient and intelligent digital temperature control system (adjustable heating temperature) to ensure precise temperature control;
3. Adopting capacitive measurement method, the sample/reagent has high accuracy and good repeatability;
4. Complies with the new national standard and can achieve multiple quality control functions.
