Product Description, Technical Parameters, and Configuration
Detection principle:
Add an oxidant to convert trivalent chromium into hexavalent chromium, then add a color developer to react with hexavalent chromium to form a purple red complex. Measure its absorbance using spectrophotometry, and after processing and calculation by a microcomputer system, directly display the total chromium content (mg/L).
