Rapid testing instrument for multi-parameter water quality of drinking water source water

The synopsis of project
The ERUN series rapid testing instrument for multi-parameter water quality of drinking water source water developed and produced by Erun Group is a solution designed specifically for on-site rapid testing of various water quality of drinking water sources in accordance with the CJ3020 national standard. The portable multi-parameter source of water quality testing instrument can mainly test parameters including chromaticity, turbidity, pH, volatile phenols, anionic surfactant, ammonia nitrogen, nitrate nitrogen, permanganate index, total coliforms, metal parameters, inorganic salts, etc. The rapid analyzer for water quality of drinking water sources can not only be used for the testing of water quality of centralized drinking water sources in urban and rural areas (including water sources for self provided domestic drinking water by various units), but also for the analysis of water quality of dispersed drinking water sources.

Note

aPrimary water source: good water quality, groundwater only needs to be disinfected, while surface water can be purified and disinfected for daily consumption.

bSecondary water source: the water quality is slightly polluted, regular purification treatment (such as coagulation, sedimentation, filtration, disinfection, etc.) can produce water quality that meets the requirements of GB5749 and is suitable for daily drinking.

cWater sources with a concentration exceeding the second level standard limit should not be used as sources of drinking water for daily life. If conditions require utilization, corresponding purification processes should be used for treatment. The treated water quality should comply with GB5749 regulations and obtain approval from provincial, municipal, and autonomous region health departments (bureaus) and competent authorities.
