GEO Calibration 2500 CM Humidity Generator and Calibrator

The GEO Calibration 2500 CM humidity generator and calibrator is a ruggedized, lightweight, highly accurate, portable humidity calibrator that is designed for extended field use in a wide range of environments. The 2500 CM humidity calibrator generates and maintains a controlled humidity and temperature environment for testing or calibrating hygrometers. It’s spill-resistant and features 3-5 minute response times, an LED display, automatic ramp/soak, front load desiccant, and custom chamber expansions.

The 2500 CM functions through the use of a dual PID controller. This controller takes the humidity and temperature values from an internal capacitance probe and further performs calculations that are then used to generate the user-entered humidity and temperature set points.
