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.
