- Product Introduction
Measurement principle
Huihuan HH-8100 CODMn / permanganate index online analyzer, using potassium permanganate oxidation method. After the water sample is acidic by adding sulfuric acid, a certain amount of potassium permanganate solution is added, and the digestion reaction is heated for a certain time. Then a reducing agent was added to reduce the remaining potassium permanganate.

Function description
· With the function of separating clean and waste liquid, automatically diverting the cleaning liquid and waste liquid into different collection buckets;
· With automatic calibration function, you can set periodic execution;
· With equal time interval measurement, whole point measurement, controlled measurement and other functions, to meet the different needs of each site;
· With automatic standard sample verification function, it can be set to be executed at a regular time every day. When the verification is unqualified, the calibration will be automatically carried out, and the verification will be carried out after the calibration is finished to ensure the linear accuracy of the equipment;
· With automatic cleaning function, the pipeline and digestion tank will be cleaned before and after measurement, and regular additional cleaning can be set to ensure the cleanliness of the pipeline and digestion tank;
· With power-on self-test and abnormal reset functions, to ensure that the equipment automatically recovers to normal state after abnormal power failure and power-on;
· With alarm functions such as insufficient reagent, heating failure, photoelectric anomaly, etc., it can ring alarm in real time and record alarm information;
· With three-level rights management function, different personnel assign different operation rights to prevent equipment data distortion or failure caused by misoperation of non-professional personnel;
· With operation log, process log and other recording functions, it is convenient to check the operation of equipment and personnel operation records.
