The GEO Calibration 2500 CM humidity generator and calibrator is a ruggedized, lightweight, highly accurate portable unit designed for extended field use in a wide range of environments. The spill-resistant construction and front-load desiccant system make this calibrator particularly well-suited for demanding field operations where reliability and ease of maintenance are critical.

Performance Specifications

Temperature range spans from 10°C below ambient to 55°C with ±0.1°C accuracy, temperature uniformity of 0.10°C, and temperature stability of 0.05°C. Humidity range extends from 5 to 95% RH with ±0.6% accuracy at 23°C, uniformity of 0.30% RH at 18 to 28°C, and stability of 0.15% RH at 18 to 28°C. Ramp and soak rates include temperature high to low at 1.50°C per minute, temperature low to high at 5.00°C per minute, humidity high to low at 5.00% RH per minute, and humidity low to high at 10.00% RH per minute.

Control and Display

Dual PID controller takes humidity and temperature values from an internal capacitance probe and performs calculations to generate user-entered set points. LED display provides clear indication of operating status and conditions. Automatic ramp/soak programming simplifies complex calibration sequences. Response times of 3 to 5 minutes enable efficient field calibration workflows.

Field-Ready Features

Front-load desiccant system simplifies maintenance, allowing desiccant replacement without requiring extensive disassembly. Spill-resistant construction protects internal components from accidental liquid exposure. Custom chamber expansions accommodate various probe sizes and configurations. The rugged design is suitable for harsh environments where conventional calibration equipment may be vulnerable to damage.
