Product introduction

The primary battery dissolved oxygen digital sensor is a new generation of intelligent water quality detection digital sensor independently developed by the company, which has patented technology. Data can be viewed, debugged, maintained, etc. through mobile phone APP or computer. It has the characteristics of simple maintenance, high stability, excellent repeatability, multi-function, etc. It can accurately measure DO value and temperature value in solution. It is widely used in wastewater treatment, purified water, circulating water, boiler water and other systems, as well as continuous monitoring of dissolved oxygen value in solutions of electronics, aquaculture, food, printing and dyeing, electroplating, pharmacy, fermentation, chemical industry and other aquaculture and tap water.

main features

◇ This product is a DO digital sensor, which can directly output RS485 signal and 4~20mA signal

◇ The product has high precision, high stability and strong anti-interference ability

◇ Automatic temperature compensation function.

◇ Without instrument, it can directly connect computer, PLC and other equipment with RS485/4-20mA signal interface for data acquisition and maintenance; It is convenient for users to integrate the sensor into the host computer system and the industrial control environment such as the Internet of Things.

◇ 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, 4-20mA output corresponding range, proportional coefficient and incremental compensation. Without instrument, it can be directly connected to computer, PLC and other equipment with RS485/4-20mA 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.

◇ The probe can be replaced.

◇ Two point correction method is adopted.

◇ The core components are from foreign brands.
