GEO Calibration 2000 SP Standard Expansion Chamber

GEO Calibration 2000 SP Standard Expansion Chamber generates and maintains a controlled humidity and temperature environment for testing or calibrating humidity and temperature sensors, also known as hygrometers. The humidity calibration range is 20 to 80%, while the temperature range is +/-5°C from room temperature. The expansion chamber can calibrate many hygrometer types, including probes, data loggers, chart recorders, and other assorted hygrometers.
