- Precision Humidity Generation
- High Temperature, High Flow Capability
- A ccurate Formulations
- 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.
