DGB-402A Portable Residual Chlorine Total Chlorine Tester Introduction: DGB-402A portable residual chlorine/total chlorine analyzer is designed and developed based on DPD colorimetry, which can directly measure residual chlorine and total chlorine in water. It is convenient, accurate and reliable to use. This method is the national standard method for determining residual chlorine and total chlorine in the field of water quality analysis, and is widely used for the determination of residual chlorine and total chlorine content in drinking water, landscape water, medical wastewater, swimming pool water, disinfectants and other samples. characteristic: 1. The 515nm LED light source is adopted, with long service life and high accuracy; 2. High performance and low power consumption single chip technology is adopted, with good man-machine interface; 3. Support single point and multi-point calibration, and support users to edit calibration curves; 4. It supports 200 groups of test data for two parameters, which conforms to GLP specification; 5. Support battery power supply and power management functions; 6. IP65 protection grade, good waterproof and dustproof performance. Technical parameters: Model: DGB-402A Instrument type: single wavelength direct reading colorimeter Measuring range: residual chlorine/total chlorine: 0.00 ～ 3.00mg/L Resolution: concentration: 0.01mg/L; Absorbance: 0.001ABS Indication error: measurement range ≤ 1mg/L: ± 0.05 mg/L; Measuring range ＞ 1mg/L: ± 5% Repeatability: ≤ 2.5% Detection limit: ≤ 0.02mg/L Light source: LED Wavelength: 515nm Calibration: more supports 5-point calibration Data storage: 200 groups of test results in total Power supply mode: 4 alkaline batteries (1.5V) Protection grade: IP65 Dimension (mm)/weight (kg): 230 × eighty-six × 47 (long × wide × High); About 0.4
