COD-580 online COD monitoring instrumentDetailed product description：

COD-580 online COD monitoring instrument features:

·Measurement of COD value in water using electrochemical oxidation (hydroxyl electrode method)
·The instrument uses sodium sulfate and glucose solutions, without the need for hazardous and harmful chemicals such as potassium dichromate and concentrated sulfuric acid, and does not produce secondary pollution
·Measurement is not affected by the color or turbidity of the water body
·New sampling system for sampling, no need for frequent maintenance and cleaning
·Adopting touch screen control, Chinese operation interface, simple operation
·COD and temperature can be displayed simultaneously through signal input pH、 traffic
·Short measurement time each time, very suitable for online rapid measurement
·Automatic calibration and measurement process of the instrument, automatic saving of test data, and remote control
·Product Certification Number: HR-2004-184
