(Authentication certificate No: CCAEPI-EP-2008-035)
u It is applied for the water quality monitoring in the rivers and lakes.
u It is applied for sewage discharge monitoring in industrial and mining enterprises and cities.
u Industrial process control: The instrument is used for water quality monitoring in many fields including environmental protection, petrochemistry, chemical industry, electricity generation, Pharmaceuticals, food security, electronics and tap water supply.
u It adopts electrochemical oxidation method (hydroxy electrode method) to measure COD value in water.
u It adopts sodium sulfate and glucose solution instead of dangerous detrimental chemical reagents such as sulfuric acid, potassium dichromate and mercuric sulfate. Thus, it will not create secondary pollution.
u The measuring time is short. Generally, it takes 6 minutes for each measurement and it is suitable for real-time measurement.
u It adopts patented sampling system and can effectively avoid blockage and reduce maintenance work.
u The measurement will not be affected by water color and turbidity.
u It adopts touch screen display and Chinese operation interface for easy use.
u It can simultaneously display COD, temperature, pH and flow rate.
u It can automatically control measurement and calibration, and automatically store measuring results. Also, it has power failure protection function.
u The RS-232 port can be used to expand RS-485 port and MOSEM network port.
u It adopts remote control and data transmission.
