WQS485pH – pH

WQS485pH is a digital output water pH sensor developed and manufactured by MJ Instruments.

With the sensor body filled internally which acts as sensor weights as well as protecting the electronic components, the sensor is well suited for long-term deployment.

The body is built with corrosive-resistant material, allowing it to be deployed at industrial discharge for pollution monitoring. Different housing is also available upon request.

With standard RS485 Modbus output, it is easy to integrate the sensor into the commercial controllers.
