pH Probe - Thermo Scientific
- pH Probe Measurement Range pH measurement range from 0 to 14
- pH Sensor Head pH sensor head is pre calibrated for pH and temperature measurement. Plug into any Datastick to yield accurate 24-bit data.
- Universal DataStick Provides conversion of sensor signals and interactive communication for measurement, calibration, configuration and diagnostics
Overview
A plug-and-play pH Sensor for use with the AquaSensors system. pH Probe connects directly to a computer or PLC for integration with industrial control systems. This allows data to be displayed and analysed, and for the instrument to be customized and calibrated without the need for intermediate controller box. The pre-calibrated pH sensor probe can be replaced or exchanged with any other type of sensor without any system downtime, saving time and money.
The Datastick pH probe is designed to be extremely strong, non-flowing, resistant to fouling and with exceptional chemical resistance. The internal electronics of the sensor are completely encapsulated and O-ring sealed, giving complete protection from humidity and moisture. An integral temperature sensor automatically compensates measurements for changes in process temperature, and a titanium ground electrode eliminates ground loop currents in the measuring electrode.
