NEW Addition to the Temperature and Relative Humidity Automatic Calibration Module (AutoCal)


The Process Sensing Technologies Group (PST) offers a digital temperature and relative humidity probe (Rotronic RMS-HCD) that is used within the Rotronic environmental monitoring system RMS. The RMS is mainly used within regulated industries where regular calibration is a requirement.

To carry out temperature and relative humidity calibrations, Rotronic has developed the HygroGen (HG2) generator, one of the fastest and most stable generators on the market.


  • Generates stable humidity and temperature conditions (<±0.1 %rh, <±0.01 °C)
  • Calibration solution for the laboratory and on-site
  • Humidity equilibrium typically in only 5 minutes for HG2-S, 15 minutes for HG2-XL
  • Calibrates multiple probes simultaneously

To reduce the manpower required for calibrations, the HygroGen has an automatic calibration module (AutoCal) that has been upgraded for the RMS-HCD digital temperature and relative humidity probe, up to 6 probes can be calibrated in one run. Within AutoCal, the user can define set points, time frames, and the option to ramp and soak. The outcome of an AutoCal run is a calibration certificate in PDF format including the reference as well as the RMS-HCD progression throughout the calibration run. Should the probes be out of specification, then the user also has the possibility to automatically adjust the probes to match the HygroGen reference probe at predetermined values.

To reduce the system downtime, the main advantage of digital sensors is that a sensor can simply be exchanged. The RMS system will automatically register any probe changes within the audit trail and these events in turn can be commented to ensure that any questions that arise during an audit can easily be explained.
