The ERUN-SP-M9000 series portable multi-parameter water pollutant rapid testing instrument for environmental enforcement developed and produced by ERUN Group is suitable for ecological and emergency enforcement departments to use in response to sudden water pollution incidents. The emergency enforcement portable water pollutant analyzer can quickly measure conventional water pollution parameters such as COD, ammonia nitrogen, total phosphorus, total nitrogen, metal parameters (chromium, hexavalent chromium, copper, nickel, zinc, iron) in water. The ecological environment multi-parameter water quality rapid testing instrument can be used for rapid inspection of outdoor sewage leakage pollution. It is equipped with a thermal printer, and the measurement index concentration can be directly read, stored, and printed. The USB interface can upload the measurement results to the supporting computer software for statistical analysis.

The ERUN series laboratory water quality testing instruments, vessels, and accessories for sewage treatment plants developed and produced by Erun Group are designed specifically for daily analysis and testing of water quality in sewage treatment plants (stations). The wastewater treatment plant water quality laboratory equipment include basic control items such as COD, BOD5, SS, oil, anionic surfactant, total nitrogen, ammonia nitrogen, total phosphorus, chromaticity, pH, and fecal coligroup count. The laboratory testing instruments for wastewater treatment plants not only include benchtop and portable water quality testing instrument hosts, but also include digestion instruments, colorimetric tubes, incubators, reagents, pipettes, volumetric flasks and other vessel accessories.
