Mini Intelligent Chemical Oxygen Demand Cod Detection Meter
This COD analyzer cod reactor analyzer manual will provide you with the necessary information for the correct use of the instrument. Please read it carefully before using the meter.Â
Attention :
1.Any liquid or foreign substance entering the inspection chamber may damage the instrument.
2.If the concentration of water samples exceeds the range of the instrument, please dilute the water sample and measure again. The measured value multiplied by the dilution times is the concentration of water sample.
3.There should be no stains, scratches, dust or fingerprints on the surface of the test tube.
Battery requirements: Please use 1.5V AA alkaline batteries.

Attention:
1.The activator is irritating,wash immediately with plenty of water if touched with the skin.2.This meter can not test the COD/Total phosphorus/Ammonia nitrogen at same time.
Â
Note:
    1.15ºC-25ºC is the best temperature for ammonia nitrogen test. It won't influence test result if Â
      Little reagents undissolved.
     2.Any solution or foreign matter inside the detection chamber,may damage the meter.
       3.If the concentration of water sample higher than the test range,please choose high test range for testing,or tested after diluted by distilled water,the test result should multiply by the dilution ratio. Â
       4.The surface of test tube should avoid waterlogging,scratch,dust, fingerprint and so on.
       5.Take action to the sequence and numbers of  activator adding.Â
       6.The reagent bag is easy to tear.
       7.The sucker of pipette can not be used crossly.
       8.It is normal if there have precipitate in the COD reagent tube.
       9.The meter should be placed on the table,it can not be tilt or shake violently when testing in other place.  Â
