NO.QJ-762 Water Quality Analyzer Main Specification:
Rationale: GB GB11914-1989 Water quality Determination of COD , potassium dichromate method
Environmental Protection Industry Standard HJ / T 377-2007 Chemical Oxygen Demand (CODcr)
Adding water samples quantitative dichromate and silver under strong acid conditions as the catalyst , after high temperature digestion of organic matter in water samples of oxygen and reducing substances will Cr6 + reduced to Cr3 +, by photoelectric colorimeter , measured reduce the amount of Cr6 + , samples the measured values and standard calibration curve samples measured by comparing a sample to find the COD value.
1Non-contact optical measurement, high accuracy, high reliability
2Single to do the total sample liquid <9ml, low operation and maintenance costs
3Integrated digestion / colorimetric module ( patented technology ) , high temperature (170 C), high pressure Digestion direct measurement , compact , fully digested , high efficiency
4Using high-resolution industrial color touch screen, easy to operate, the amount of information -rich
