Introduction: The machine adopts the DPD national standard method, which can detect the residual chlorine and total chlorine indicators in the water body. The colorimetric method of the test tube eliminates the need for tedious calibration of standard samples and enables rapid detection. In addition, the machine is equipped with a carrying case and a large-capacity ion battery. It can work outdoors for a week, and it can also be equipped with an adapter to switch indoor work, which improves work efficiency. It can be widely used in universities and colleges, scientific research institutes, sewage treatment plants, environmental monitoring stations, petrochemicals, papermaking, pharmaceuticals, printing and dyeing, textiles, leather, wine, dairy, electronics, municipal engineering and other industries Features: 1. DPD national standard method, accurate detection 2. Chinese keyboard, LCD backlit liquid crystal display, direct reading of concentration 3. Test tube colorimetry, no need for tedious calibration of standard samples, rapid detection can be achieved 4. Built-in time memory system, large-capacity storage card 5. Equipped with large-capacity ion battery, outdoor work can be continuous for one week 6. Equipped with adapter to switch indoor work Technical Parameters: Detection index: residual chlorine total chlorine Repeatability: ≤±5% Resolution 0.001 Optical stability: ≤±0.005A/20min Measurement error: ≤±5% The lowest detection limit: 0.001 Measurement accuracy: ≤±5% Measuring range: 0-3mg/L Measuring principle: DPD spectrophotometry
