Product Description

China Factory Rs485 Digital Water Nitrate Sensor 4-20 Nitrate Probe for Water Quality Monitoring Test Instruments Type

Products Description


A digital water nitrate sensor is a device designed to measure the concentration of nitrate ions (NO3-) in water. It is commonly used in applications such as environmental monitoring, agriculture, water quality analysis, and research.



The online nitrate sensor is used to test the content of nitrate in water. It can be fast, simple, accurate, and economical, and can be monitored online in real-time and integrated nitrate ion, pH, and reference electrode to compensate for the pH and temperature in the water body automatically. It can be directly installed, more economical and environmentally friendly, convenient and fast. Using RS485 output supports Modbus, easy to integrate.



* Digital sensor, RS-485 output, support MODBUS
* More economical and environmentally friendly, can be monitored online in real time
* Automatically compensate pH and temperature in water
* High precision and high stability.
