Water Quality Nitrite Sensor, 0-10 ppm

This is a 0–10 ppm ion-selective electrode (ISE) sensor for monitoring nitrite concentrations in water, using the coated-electrode method to ensure stable detection. It supports RS485 and MODBUS/RTU communication, with a resolution of 0.01 mg/L and an accuracy of ±5% F.S. or ±3 mg/L. The nitrite sensor is suitable for water treatment engineers, environmental monitoring personnel, and system integrators, and is widely used in wastewater treatment, drinking water monitoring, and aquaculture water quality management.

Feature

• Digital water quality sensor with direct RS-485 digital signal output, supporting MODBUS/RTU.
• The ion exchange membrane head of the SUCH nitrite ion water quality sensor is replaceable, resulting in low maintenance costs.
• Does not consume chemicals and has no micro-pores, eliminating the risk of clogging in wastewater.
• 0-10 ppm water quality sensor features low power consumption and an internal circuit designed for interference resistance.
• Nitrite ion sensor features a built-in temperature sensor for automatic temperature compensation.
