LFEC-2002 Arsenic(As) Analyzer
Introduction
LFS-2002 water quality analyzer applies the optoelectronic signal detection module.
Over 40 monitoring parameters are involved, including the hypermanganate index, chemical oxygen demand, total chromium, arsenic, hexavalent chromium, mercury, iron, manganese, nickel, antimony, silver, copper, aluminum, zinc, lead, total nitrogen, ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, total phosphorus, phosphate, sulfide, residual chlorine, total chlorine, cyanide, aniline, volatile phenol, formaldehyde, anionic surfactant, etc. The instrument is mainly used for monitoring in real time municipal household sewage, drainage of pollutant sources, groundwater, underground water, etc.
Reagent Preparation:
The original factory provides a set of matching reagents, which can be used for 3 months if it is used 8 times a day.
The application, procurement, storage, and use of reagent raw materials must comply with the requirements of applicable laws and regulations!
