Analog controller for pH/ORP measurement
Analog field monitor for the low and high ohms pH measurement – reliable by means of automatic temperature compensation for NTC, Pt100 or Pt1000:

• • Low and high ohm pH input to connect also external sensors
  • Reliable measurements by automatic temperature compensation with NTC, Pt100 or Pt1000
  • User-friendly operation by intuitive menu structure

The pH 298 is an economical and metrologically flexible solution for use in the field. Consequent galvanic separation of all outputs.

The pH 298 is equipped with a low and a high ohm signal input. Thus, the monitor not only can be operated with WTW SensoLyt® measuring probes/electrodes and WTW ProcessLine® electrodes. If the adapted probes are not equipped with an integrated NTC sensor, you can connect any NTC, Pt100/Pt1000 sensors to measure temperature and for automatic temperature compensation.
