Nitrite sensor

Nitrite is a basic type of conventional water quality monitoring digital sensors; industrial
online electrode, PVC membrane made of ion-selective electrode, selective testing of ammonium
ion content in water, fast response speed, accurate measurement. Built-in temperature sensor,
automatic temperature compensation, suitable for online long-term monitoring environment.

Features

Digital sensors, direct transmission RS485 digital signal, support MODBUS/RTU
Built-in temperature sensor for automatic temperature compensation
Innovative replaceable ionization heads, low maintenance with replacement heads
3/4” NPT top and bottom mounting thread design for easy installation
Low power consumption of the sensor and anti-jamming design of the internal
circuits
