Dew Point Apparatus



Determines the water vapor content of gaseous fuels by measurement of the dew point temperature, followed by calculation of the water vapor content.

  • Rugged construction
  • Stainless steel sample chamber with incorporated “target mirror”

The Dew Point Apparatus consists of a closed stainless steel dew point chamber containing a highly polished stainless steel “target mirror” and sample inlet and outlet control valves. The chamber is chilled by refrigerant following through the outer cooling jacket, preventing any refrigerant contact with the test sample. The thermometer is inserted into the mirror support structure, providing the temperature of the “target mirror.” As the sample flows in the chamber and is deflected across the surface of the mirror, the temperature at which condensation collects on the mirror is recorded as the dew point of the sample.

  • Cooling Chamber with 1/4" gas needle valve
  • Stainless Steel Block with 1/4" gas needle valve
  • Viewing Mirror
  • Thermometer Guard
