product description
NIPm-3000 multi-parameter water quality online analyzer adopts sequential injection-spectrophotometry technology. The instrument uses the same technology platform to sequentially add water samples, reagents, etc. into the digestion tank to carry out fully automatic processes such as mixing, digestion, colorimetry, and cleaning. The concentration of the water sample is automatically calculated by the absorbance before and after the reaction, and the multi-parameter quantitative analysis of COD, ammonia nitrogen, total phosphorus, total nitrogen and permanganate is realized.

1. Fully automatic operation: automatic calibration of zero point and range, automatic uploading of abnormal records to alarm, automatic control and automatic cleaning of water pump start and stop, and automatic unmanned operation;
2. Data recording: After power off and on again, the data is automatically reset to the state of restarting the test, the original data and operation log can be saved for more than one year, and it supports data collection, storage, processing, query, display and output;
3. Data output: analog 4-20mA, digital RS485/RS232;
4. System security: set three-level management authority, ordinary user/debugger/administrator authority, can automatically record and repair system alarm failure points, and has a visual safety mask design; interface operation: graphical interface, Prompt menu, easy to operate and remote maintenance, easy to operate and small maintenance;
5. Intelligent diagnosis: intelligent diagnosis of pipeline blockage, leakage, lack of reagents, abnormal information, and automatic uploading of alarms for instrument circuit failures;
6. Remote quality control: remote quality control, remote standard sample verification, remote monitoring of instrument status, and remote online software upgrade;
7. Range switching: automatic range switching, automatic verification of standard samples, automatic determination of recovery rate of standard addition, automatic temperature compensation;
8. Calibration: automatic calibration of zero point and span, separation of waste liquid, automatic cleaning, perfect user authority management, and intuitive measurement;
9. Authority management: perfect user authority management, intuitive measurement;
10. Standard sample verification function: with manual and automatic standard sample verification function

It is used for online monitoring of water quality in sewage treatment plants, water plants, surface water, drinking water sources, aquaculture, industry and other fields.
