GEO Model 1000 SP Humidity Generator

Compact, light weight humidity generator featuring quick-change desiccant and improved air flow.

The Model 1000 Benchtop Humidity Generator operates through use of a multifunction CPU in conjunction with other peripheral cards to perform calculation and control functions.

The embedded computer control system allows the MODEL 1000 to generate known humidity levels unattended, freeing the operating technician from the task of system monitoring and adjustment.

A computer may be connected via the USB interface allowing remote setpoint control and continuous data feed.
Humidity and temperature setpoint values are input by the operator from the front panel controller or via our DFB Desktop Software while visual indications of system status are displayed in real time.
