TR-205H Total Chromium Analyzer (TR900 Series)

Instrument Overview:

The TR-205H total chromium analyzer is improved based on the authoritative certification method GB7466-87 "Determination of Total Chromium in Water Quality". In an acidic solution, trivalent chromium in the sample is oxidized to hexavalent chromium by potassium permanganate. Hexavalent chromium reacts with diphenylcarbazide to form a purple red compound. The absorbance of the sample at a specific light source wavelength is detected by spectrophotometry using an imported cold light source and narrowband interference technology. After automatic data processing by a microcomputer, the total chromium concentration of the sample is directly displayed in mg/L.
