Model 2500
Model 9500
Automated “Two-Pressure” Humidity Generation System
The Model 9500 Humidity Generator is a system capable of producing known humidity values using the fundamental, NIST proven, “two-pressure” principle. The 9500 is capable of continuously supplying an accurately known relative humidity, dew point, frost point, parts per million, or other calculated values for instrument calibration and evaluation as well as precision environmental testing. This system will automatically generate manually entered humidity and temperature set points as well as user created multipoint humidity and temperature profiles. All desired humidity’s, temperatures, test pressures, flow rates, and time intervals may be programmed. Visual indications of system status are displayed in real time on the computer monitor.
