Portable Chemical Oxygen Demanding Testing Lab System Analyzer
Products Description
It is designed and manufactured according to “Water quality-Determination of the chemical oxygen demand-Fast digestion-Spectrophotometric method” and ” Water quality―Determination of ammonia nitrogen― Nessler’s reagent spectrophotometry” applicable to many testing standards at home and abroad.
Features (01)Quick and accurate determination of chemical oxygen demand (COD) in surface water, reclaimed water, municipal wastewater and industrial wastewater. Concentration direct reading.
(02)IT can determine Ammonia nitrogen, COD high range and COD low range water samples simultaneously and support both colorimetric cuvette and colorimetric tubes.
(03)The independent dual optical system has the advantages of direct reading, high accuracy, long service life and more stable.
(04)The 3.5 inch color LCD screen, humanized operation hint, simple to use.
(05)Self-calibration function of the instrument can be calculated and stored according to the standard sample, without manual production of curves.
