摘要：An apparatus for measuring dew-point of a gas stream includes a sensor cell having a probe, means for cooling the probe, means for transmitting light to the probe surface in a pressurized chamber, means for receiving returned light scattered from the cooled probe surface, and means for determining dew-point from a reduction in scattered light intensity. The probe surface is provided in its center with a depression of low angle.
