Product introduction

The ammonia nitrogen digital sensor is an intelligent ammonia nitrogen monitoring digital sensor developed by our company. It is made of ammonium ion selective electrode based on PVC membrane. It is used to test the ammonium ion content in water, with temperature compensation, to ensure that the test is fast, simple, accurate and economical.

main features

◇ This product is a ammonia nitrogen digital sensor, which can directly output RS485 signal.

◇ Automatic temperature compensation function.

◇ Without instrument, it can directly connect computer, PLC and other equipment with RS485 signal interface for data acquisition. It is convenient for users to integrate sensors into industrial control environments such as host computer system and IoT system.

◇ Use mobile phone APP to collect, debug and maintain data of sensors through wired (OTG cable and 485 to USB module) or wireless networks (such as WIFI, GPRS and other wireless networks).

◇ The sensor can be set through RS485 communication, such as slave address and baud rate, online calibration, factory restoration, proportional coefficient and incremental compensation.

◇ Two point correction method is adopted.

◇ The core components are from foreign brands.
