KWS-690 Digital Dissolved Oxygen Sensor , Directly Outputs RS485 And 4~20mA Signals , Continuously Monitors Dissolved Oxygen Values ​​in Solutions

Product introduction

The Galvanic Cell method dissolved oxygen digital sensor is a new generation of intelligent water quality detection digital sensor independently developed by our company. It can check, calibrate, maintain through mobile phone or computer. It’s easy to maintenance, with high stability and good repeatability. Its’ function it to test the DO value and temperature of liquid. It is widely used in waste water treatment, purified water, circulating water, boiler water and other systems as well as continuous monitoring of dissolved oxygen values in solutions such as electronics, aquaculture, food, printing and dyeing, electroplating, pharmaceutical, fermentation, chemical and other farming 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.
• No need for instrumentation, can directly connect to computers, PLC and other devices with RS485/4-20mA signal interface for data acquisition and maintenance; it is convenient for users to integrate sensors into the industrial computer system such as PC system and IOT.
• The sensor can be set by RS485 communication, slave address and baud rate, online calibration, factory reset, 4-20mA output corresponding range , proportional coefficient and incremental compensation.
• Two-point calibration method is used.
• Power off protection > 10 years.
