WTW Field monitor pH 298 NTC

Analog field monitor for the low and high ohms pH measurement - reliable by means of automatic temperature compensation for NTC.
  • low and high ohm pH input to connect also external sensors
  • Reliable measurements by automatic temperature compensation with NTC
  • user-friendly operation by intuitive menu structure
The pH 298 is an economical and metrologically flexible solution for use in the field. Thanks to its integrated lightning protection, the fail rate by secondary lightning effects is minimized. 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 sensors to measure temperature and for automatic temperature compensation.
