The Michell Instruments VDS-3 Dew Point Generator is a sophisticated computer controlled dew point generator that operates in the range of -148 to 68°F (-100 to 20°C). Individual three stage mass flow controllers select precise proportions of wet and pre-mixed air. Humidity injection is achieved by a liquid mass flow controller and controlled evaporation system. The Vapor Delivery System (VDS) gives repeatable and flexible control of the generated dew point and can be programmed with up to 13 presets that can be activated manually or as part of an automatic calibration program.
