The DG-4 dewpoint generator can regulate the water vapor content of an air stream based on relative humidity (within 1%) or dewpoint (0.1oC). It is useful for creating accurate consistent vapor pressure or humidity profiles even in fluctuating environmental temperatures.

The RH-300 water vapor analyzer is a high resolution (0.001% relative humidity), wide range (0-100% RH non-condensing) flow-through analyzer that can display and output in units of relative humidity, dew point, water vapor pressure, and water vapor density.  The RH-300 is ideal for determining water loss rates and measuring water vapor partial pressure for gas sample dilution corrections.
