Using multi-point measurement module, quantitative more fast and accurate. |
|
A new type of discharge valve has been jointly developed, which effectively reduces the interference of taking liquid and prolongs the life of the discharge valve. |
|
The initial signal of measurement and measurement can be automatically initialized, without manual adjustment, improving operation and maintenance efficiency. |
|
The amount of reagent is greatly reduced, about 40% less than before. |
|
The data stability is improved, which is about 30%-50% higher than before. |
|
The system upgrade supports USB flash drive upgrade without remote operation, improving O&M efficiency. |
- 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 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.
