WS pH / Temperature Measurement Sensor
PRODUCT OVERVIEW
The pH probe with the integrated temperature sensor was designed for use in challenging conditions. The possible applications range from pure spring water all the way to wastewater. The special Plastogel (c) technology increases service life and thereby reduces the need to replace the cartridge.
Thanks to the low energy consumption and quick response time, the pH sensor can be used in mobile and stationary applications.
The intelligent sensor saves data such as calibration directly in the sensor. This enables 'plug and play' usage without requring calibration. Transfer of data is accomplished by means of a Modbus protocol.
