NHN-220 Ammonia Nitrogen Sensor

Type:Water Quality Sensor Specification: diameter 30mm; length 189mm Material: POM; customizable Color: Black Model: NHN-220 OEM:Available MOQ:1PCS Payment:T/T
Product Description
Product Description:

NHN-220 is a basic conventional water quality monitoring digital ammonia nitrogen sensor; Made of industrial online electrodes and PVC membrane ammonium ion selective electrodes, it selectively tests the ammonium ion content in water with fast response speed and accurate measurement. Built in temperature sensor with automatic temperature compensation, suitable for long-term online monitoring of environmental use.
characteristic:
1. Digital sensor, directly outputs Rs-485 digital signal, supports MODBUS/RTU
2. Built in temperature sensor with automatic temperature compensation
3. The innovative ammonium ion membrane head is replaceable, and the maintenance cost of using the replacement membrane head is low
4. 3/4 "NPT upper and lower installation thread design, easy to install
5. Low power consumption of sensors and anti-interference design of internal circuits
6. Optional addition: PH and potassium ion compensation to reduce interference in testing
Note: Choose pH and potassium ion compensation based on the medium pH and ion interference situation
