1、 Product Introduction:
The instrument complies with national standardsAutomatic water quality samplerTechnical Requirements and Testing Methods (HJ/T372-2007) is a multifunctional monitoring instrument that integrates flow measurement and water sample collection. It has the characteristics of small size, light weight, and easy portability. It has been awarded the National Key New Product Certificate by five national departments and is the winning product of the Water Environment Capability Monitoring Instrument and Equipment of the State Environmental Protection Administration. Suitable for environmental monitoring stations at all levels, sewage treatment plants, water conservancy, water affairs, and research institutes, to automatically sample water samples from industrial pollution source discharge outlets, rivers, lakes, seas, and other sources. This instrument is developed based on the requirements of national environmental monitoring technical specifications, combined with the environmental pollution situation in China and the needs of environmental monitoring departments at all levels. It is an intelligent sampler that can collect sewage samples by time, volume ratio, and constant flow ratio. The sampler is well-designed and powerful, and can complete various sampling tasks according to user needs. It also has a flow meter function and is an essential instrument for daily average concentration of pollutant discharge.
