The HygroCal100 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 allows 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 allows you to automate your calibration procedure with ease and will provide a complete logged output of all probes under test against the reference instrument in csv format, ready to download to your USB memory device. Coupled with an Optidew 401 chilled mirror hygrometer, the HygroCal100 becomes a powerful transportable calibration facility. The HygroCal100 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.
