DGB-423 Photoelectric Colorimetric Water Quality Analyzer
Introduction: DGB-423 photoelectric colorimetric water quality analyzer adopts new LED test technology, integrates LED light source with specific absorption peak wavelength, built-in standard curve, directly uses the colorimetric tube as the measurement container, and is compact and convenient for users to operate and carry. This series of products can measure ammonia nitrogen parameters (this series of instruments can be expanded to customize items such as ammonia nitrogen, total phosphorus, permanganate index, aluminum, total hardness, residual chlorine, total chlorine, chlorine dioxide, urea, etc.), suitable for On-site measurement or laboratory analysis of surface water, industrial wastewater, medical wastewater, landscape water for sewage regeneration, domestic drinking water, swimming pool water, etc. Features: 1.LED test technology, small size and stable signal; 2. LCD liquid crystal display, with backlight, LCD contrast and backlight time can be adjusted; 3. Has a good Chinese man-machine interface, supports IP65 protection level; 4. Automatically lock the measured value and read the measurement result directly without conversion; 5. Convenient operation, can directly use the colorimetric tube as the measuring container; 6. Built-in calibration curve, can be directly measured; 7. Support multi-point calibration (up to 5 points) to meet high-precision measurement requirements; 8. Support GLP specifications to meet data storage, search, delete and print functions; 9. With automatic shutdown function and power-off protection function, the automatic shutdown time can be set to reduce power consumption and ensure data security; 10. Support battery power supply (4 AA alkaline batteries) or USB port direct power supply; 11. With USB interface, support connection with PC, printer, etc.; 12. Support firmware upgrade, allow function expansion and application expansion to meet the measurement needs of special users; 13.
