Description

The G2 produces highly accurate humidity values based on RH Systems’ unique hybrid combination of the NIST proven “two-pressure” and “two-temperature” humidity generation techniques. It delivers a humidified gas stream, accurately controlled to a variety of user selectable humidity parameters such as %RH, dew point, frost point, ppm, or vapor pressure. By accurately measuring the temperature and pressure at the point where the humidified gas is utilized, the G2 automatically adjusts for changes in dynamic conditions such as heat load or ambient pressure variation.

Features

• Precise generation of humidity controlled gas flow
• High accuracy two-pressure / two-temperature principle
• Flow rates up to 100 liters per minute
• Controls %RH, Dew Point, or other humidity parameters
• Simultaneous measurement of up to 3 external temperature probes
• Measurement of pressure and temperature at point of gas use
• PC software for system control and data acquisition
• Optional touch panel for control and status indication
