Portable water quality heavy metal rapid detector
Adopting electrochemical rapid detection method---Anodic stripping voltammetry,Combining national standard methods---Photometric colorimetry,It can be applied to on-site emergency detection (such as emergency monitoring of water pollution accidents), as well as heavy metal detection and analysis in laboratories. It is suitable for environmental protection bureaus, water management bureaus, monitoring stations, water companies, and disease control centers, and can be used for monitoring surface water, groundwater, seawater, industrial wastewater, drinking water, or other environmental water bodies.
the productScalable measurement of indicators such as hexavalent chromium, nickel, manganese, etc. Can meet the needs of environmental monitoring agencies at all levels, environmental science institutes, universities, water treatment plantsOn site rapid detection of heavy metals in water quality by enterprises and others
