Chemical Oxygen Demand English Language Menu LCD Display ISO Certification
Features of NANBEI chemical oxygen demand :
u English language menu and LCD display for easy use
u It adopts dichromate colorimetric method.
u Direct reading of COD results and no need to analyze by other means such as titration.
u 2 point calibration (zero COD and full scale calibration)
u Measuring results can be viewed, deleted and printed. Up to 200 sets of measuring data
can be stored and it can be connected with TP-16 printer.
u It adopts digestion method of sealing reflux and can conduct simultaneous digestion of 21 samples for low energy consumption.
u The digestion temperature can be adjusted from ambient temperature to 165℃. Also, it is equipped with over temperature alarming system.
u The digestion time can be set from 0 to 120 min. It will be power off after response.
