Digital measurement of pH with built-in electrode quality monitoring - usable in all areas of the wireless lab, field and depth profile measurement

  • Safely measured values due to signal processing in the sensor
  • Easy electrode replacement thanks to calibration data stored inside sensor
  • Sensor quality monitoring by QSC function

pH electrodes are the most frequently used electro-chemical sensors. They are used practically in all areas of lab and field measurement. At the same time, the deliver the most sensitive measuring signals and must be serviced and calibrated at regular intervals.

This is exactly where the concept of IDS sensors comes in. Digital data transfer is safe against interference, allows the use of long cables and permits important additional information such as calibration data and sensor recognition.

WTW offers a wide variety of IDS pH electrodes for field use, all the way to special applications in the lab. The QSC function allows monitoring of the current sensor status with all IDS pH electrodes.

WTW's proven pH electrodes are now available as sustainable plug head versions. The universal plug head fits the sensor with wireless functionality – disturbing cables are no longer required.
Furthermore it can be connected to AS/IDS-x cables with lengths of up to 100 m. With this new technology WTW significantly expands the range of applications and the measuring comfort of its pH electrodes.
