The GEO Calibration Hygro-Mini portable humidity generator is the smallest available unit offering variable control for both humidity and temperature. Designed specifically for field calibration applications, this battery-powered unit delivers laboratory-grade performance in a compact, lightweight package suitable for hard-to-reach locations and low volume probe facilities.

Performance Specifications

Temperature range spans 18 to 35°C with ±0.4°C accuracy, temperature uniformity of 0.20°C, and temperature stability of 0.10°C. Humidity range extends from 5 to 85% RH at 23°C with ±1.0% accuracy, uniformity of 0.40% RH, and stability of 0.15% RH. Ramp and soak rates include temperature transitions at 1.00°C per minute in both directions, with humidity transitions at 3.00% RH per minute for decreasing humidity and 3.00% RH per minute for increasing humidity.

Portable Operation

Battery power enables true portability for field calibration tasks, with two hours of operating life sufficient for typical calibration sessions. Any programmed set-point can be reached within three minutes, minimizing wait times and maximizing productivity. The orientation of the unit does not affect accuracy, allowing placement in the most convenient position for the application.

Design Benefits

The compact form factor makes the Hygro-Mini ideal for mobile applications where space is limited. Its lightweight construction reduces operator fatigue during field use. PID controller ensures precise regulation of conditions. This calibrator is particularly suited for field service organizations, mobile calibration laboratories, and facilities requiring calibration capabilities at multiple locations without transporting large equipment.
