HLTCr1-2 typeTotal chromium water qualityOnline monitoring analyzer

Working Principle:In acidic solution mediumAt a certain temperature and pressure, chromium in different valence states and forms in water samples is oxidized to hexavalent chromium by potassium persulfate or potassium permanganate. Hexavalent chromium ions react with diphenylcarbazide to form a purple red complex. By measuring the absorbance, the total chromium content in the water sample can be indirectly obtained.

Performance parameters:test scope （0.05-30) mg/L has automatic range switching function, which can achieve automatic measurement of water samples with different concentrations.
