The Rotronic HygroCal100A Humidity Calibrator provides a stable test chamber for evaluating the performance of relative humidity sensors across a wide range of 5 to 95% relative humidity. Its intuitive design allows probes under test to be fully integrated with the chamber and user interface, enabling up to seven probes with various diameters and output signals to be powered, monitored, and logged simultaneously by one self-contained unit.

The calibrator accommodates probes from 0.3 to 1 inch (8 to 25.5 mm) in diameter, as well as complete data loggers or room-mount humidity sensors. The 4.3-inch LCD touchscreen runs a powerful user interface displaying all measured values from the reference and probes under test, along with a graphical trend indication of chamber stability. The system can automate complete calibration procedures with ease, providing comprehensive logged output in CSV format directly to a USB memory device, minimizing time spent taking readings.

With 2GB of internal memory, eight probe ports, and the ability to calibrate up to seven probes simultaneously, the HygroCal100A is ideally suited for both on-site verifications and laboratory use. Typical applications include pharmaceutical manufacturing, where precise humidity calibration is critical for quality assurance, and food manufacturing, where environmental monitoring ensures product quality and safety.
