Product Features

1. Direct Immersion Measurement：The PUVNO3-900 Spectroscopic Nitrate Online Analyzer adopts probe direct immersion measurement mode, eliminating the need for complex sampling and pre-processing procedures, and realizing in-situ continuous monitoring of water quality.

2. Environmentally Friendly & No Secondary Pollution：The whole detection process does not require any chemical reagents, avoiding reagent consumption and secondary pollution to water bodies, and complying with green environmental protection testing standards.

3. Fast Response & Real-time Monitoring：With short response time, the device supports 24/7 continuous measurement, and can timely feedback the dynamic changes of nitrate concentration in water bodies.

4. Automatic Cleaning & Low Maintenance：The sensor is equipped with an automatic cleaning function, which can effectively reduce the adhesion of impurities on the probe surface, lower the frequency of manual maintenance, and extend the service life of the device.

5. Multiple Protection Functions：The sensor has positive and negative reverse connection protection for power supply, as well as protection for RS485 A/B terminal connection to power supply, avoiding device damage caused by incorrect wiring and improving the stability and reliability of operation.

6. Optional Wireless Data Transmission：The device can be equipped with a wireless data transmission module according to user needs, supporting remote data transmission and management, and facilitating centralized monitoring of multiple monitoring points.

• Drinking water, surface water, groundwater, and industrial production process water

• Sewage treatment plants, especially for continuous monitoring of nitrate concentration in sewage aeration tanks and precise control of the denitrification process in biological treatment
