Portable water quality rapid analyzer for farmland irrigation water

The synopsis of project
The ERUN series portable water quality rapid analyzer for farmland irrigation water developed and produced by Erun Group is a solution designed with reference to the "GB 5084". The water quality testing instrument of irrigation water for crops is suitable for local ecological environment authorities, agricultural and rural authorities, water conservancy and other authorities to test the water quality of agricultural irrigation water sources using surface water and groundwater. The water quality analyzer of agriculture and rural areas can mainly be used to test the pH, temperature, suspended solids, BOD5, CODCr, anionic surfactants, chlorine ions, sulfides, salinity, lead, cadmium, hexavalent chrome, mercury, arsenic, thermotolerant coliforms, aerobic bacterial count, etc. of irrigation water for paddy fields, dry land crops, and vegetables.
