Yosemitech Y563-B nitrate sensor employs an industrial-grade online electrode fabricated with a PVC membrane-based ion-selective electrode. It selectively detects nitrate ion content in water, featuring fast response and accurate measurement. With a built-in temperature sensor, it supports automatic temperature compensation, making it suitable for long-term online monitoring applications. It can measure nitrate levels in natural water, surface water, groundwater, produced water, and aquaculture environments.

- Digital sensor, RS-485 output, supports MODBUS;
- No need for electrolyte, strong anti-interference, no frequent calibration required;
- Built-in temperature sensor, automatic temperature compensation;
- Ion electrode method, no need for electrolyte, electrodes can be replaced separately, easy to maintain.
- Built-in calibration parameters, convenient for on-site use and secondary calibration.
