GEO Calibration 4000 EXP Humidity Generator and Calibrator

Description

The GEO Calibration 4000 EXP humidity generator and calibrator is a vertical temperature and humidity generator that supports large calibration equipment. This unit features a temperature-controlled door, which is designed to maintain internal temperature and remain unchanged due to outside ambient temperature changes.
The 4000 EXP unit has a 3-5 minute response time and can perform automatic ramp/soak. Its 30 liter square chamber is suitable for calibrating data loggers, chart recorders, and probes, and the unit is also engineered to support legacy hair hygrometers.
