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

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.
