IDS ORP electrodes

WTW sensors digital IDS ORP electrode SensoLyt® 900 ORP-T

IDS ORP electrodes are used to measure oxidation or reduction potentials in waterous solutions - with integrated temperature sensor

  • Safe measured values due to signal processing in the sensor
  • Integrated temperature sensor NTC 30 kOhm for precise value documentation
  • Best possible GLP support by documenting the sensor data

ORP electrodes deliver a sensitive voltage signal from reactions in waterous solutions, where the reaction partners exchange loads on the Pt metal surface of the electrode. The scale is comparable with that of pH measurement. Typical areas of use are the monitoring of the disinfection effect, the determination of ORP potentials in biochemical reactions, measuring in waters of different quality and more.

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