Description
Overview
GAOTek portable rapid chemical oxygen tester is determined by spectrophotometry method. A special reagent containing a composite catalyst is used to speed up translation and resist interference from chlorine ions, the redox reaction is quickly carried out in the digester to produce chromium trivalent.
