Humidity Generator - Rotronic HygroCal100 Advanced

Automated Humidity Probe Validation

Key features

  • HC2A-S as reference probe and calibration of 7 probes simultaneously
  • Truly portable at 3.2kg, and completely self-contained
  • Intuitive user interface makes automating probe verification simple
  • Integral battery pack means validation can be done without access to services
  • Automated validation procedures for complete hands-off probe verification
  • Internal calibration correction cycle ensures continued confidence
  • Optional chilled mirror reference hygrometer, allowing use as a calibrator
  • Download log files and remote control with the free HC100A software


The HygroCal100 Advanced provides a stable test chamber to quickly evaluate the performance of relative humidity sensors across a wide range of 5 to 95% relative humidity. Its intuitive 4” touch screen display and interface allow the probes under test to be fully integrated with the chamber and user interface (UI), so up to 7 probes with a variety of diameters and output signals can be powered, monitored, and logged simultaneously by one self-contained unit. The HygroCal100 Advanced allows you to automate your calibration procedure remotely over the free software or directly over the device with ease and will provide a complete logged output of all probes under test against the HC2A-S reference instrument in csv format, ready to download to your PC with the software. Coupled with an optional Optidew 401 chilled mirror hygrometer, the HygroCal100 Advanced becomes a powerful transportable calibration facility. The HygroCal100 Advanced can optionally be fitted with a high-capacity battery pack, which can power the generator and 7 sensors under test for up to 8 hours. The unit can also run from mains power while charging the battery.
