BF-105S hexavalent chromium analyzer
Detection principle:
The chromogenic reagent reacts directly with hexavalent chromium to form a purple red complex, and its absorbance is measured by spectrophotometry. After processing and calculation by a microcomputer system, the hexavalent chromium content (mg/L) is directly displayed.
Scope of application:
It can be widely used in colleges and universities, research institutes, sewage treatment plants, environmental monitoring stations, electroplating, petrochemicals, papermaking, pharmaceuticals, printing and dyeing, textiles, leather, brewing, dairy industry, electronics, municipal engineering and other industries.
