Product Description
The Michell HG10 Humidity Calibration System is a highly flexible computer-controlled automatic calibration system for humidity sensors. The HG10 is capable of repeatable generation of temperature and relative humidity set points over the range 1 to 95% RH
(-50 to +50°Cdp) at temperatures of +20 to +50°C with excellent stability. The supplied chilled mirror reference instrument provides traceability directly to national standards, and makes the system suitable for use in high-level calibration laboratories.
The supplied PC software allows the creation of automatic calibration programs, for evaluating the performance of humidity sensors over a range of operating conditions. The measured values from the chilled mirror reference are used in a closed control loop to enable repeatable set point generation, time and time again.
