Common faults and treatment methods of COD measuring instrument The COD measuring instrument adopts the cold light source display technology, and the life of the light source lamp is as long as 100,000 hours
.
The instrument can accurately measure COD, ammonia nitrogen, total phosphorus, total nitrogen, turbidity, etc.
, and can quickly and accurately measure the chemical oxygen demand of sewage in the laboratory and field
.
It is the experimental equipment for environmental monitoring stations, environmental engineering technicians, and enterprise laboratories
.
Some common fault analysis of COD analyzer: 1.
The screen is not bright or black after the host is turned on (1) Check whether the power supply of the power supply is normal (2) Check whether the cod analyzer itself has electricity 2.
The blank solution of the cod analyzer cannot be reset to zero (1) Restart the instrument (2) Check whether the monochromatic light in the colorimetric cell exists or pass normally (3) Whether the upper cover of the instrument is closed when the instrument is turned on (4) Check whether the blank solution is turbid (5) Use Can the air return to normal? 3.
If the historical data cannot be viewed, confirm whether it has been saved after the measurement results.
The detected results are not zero.
(1) Check whether the currently used curve value (Kv) is set to 0 (2 ) When measuring the water sample, whether all the samples including the blank are the same sample (3) Check whether the monochromatic light in the colorimetric cell exists or passes normally 4.
There is no response when the key is operated (1) Check whether In a specific setting interface, it is normal that some key operations do not respond (2) Restart the instrument 5.
The measurement result is unstable, and the value fluctuates up and down (1) Check whether the colorimetric solution is turbid, and observe whether there is any suspended matter (2) After the water cooling is completed, whether it has been mixed repeatedly when transferring to the cuvette (3) Whether there is liquid suspension on the outer wall of the cuvette (4) Whether the instrument has been preheated before colorimetry (5) Use air for normalization.
Zero, observe whether the transmittance is stable (6) Whether the colorimetric upper cover is sealed properly, and there is direct interference from strong light The above is the introduction of common faults and processing methods of the cod tester.
I believe you will have a corresponding understanding of this after reading , you can use it as a reference, I hope it will help you
