RH Systems Humidity Generator G9

The Model G9 produces highly accurate humidity values based on the NIST proven "two-pressure" humidity generation technique. This system will generate a variety of humidity values such as %RH, dew point, frost point, ppm, or vapor pressure. The system is computer controlled, allowing it to run at fixed points, or multipoint profiles, completely unattended. Principle of Operation Using the two-pressure technique, humidity is generated by fully saturating gas at a known temperature and pressure, then reducing the pressure to a lower value (typically ambient) at the same temperature. The humidity produced by this technique is determined solely from measurements of temperature and pressure, and does not rely on measurement of the water vapour content. High Temperature, High Flow Capability With chamber temperatures up to 85°C and flow rates to 150 standard liters per minute, the G9 boasts the highest temperature, highest flow rate capability of any commercially available two-pressure humidity generator.
