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.
