Detailed Product Description

Model HH-6 COD Analyzer

------serial products of environmental protection analysis instrument

   Model HH-6 COD (chemical oxygen demand) Analyzer is designed by the optical analysis principle to give a precise COD measurement. In this method, the catalytic and sealing digestion technique, the cold light source, the narrow-band interference technique and the microcomputer is used. And by these, a COD value can be measured rapidly and exactly, and displayed in the LCD display directly; especially, in the measurement process, the digestion step can complete only within 10 minutes.

   This instrument is widely used by environment monitoring departments, sewage disposal works, mineral enterprises, and laboratories of science and research academy, etc.
