Industrial Multifunction Dew Point Transmitter

Dew point is the temperature to which air must be cooled for water vapor in it to condense into dew or frost. At any temperature there is a maximum amount of water vapor that the air can hold. This maximum amount is called water vapor saturation pressure.Dew-point transmitters are calibrated to measure dew point against a chilled mirror reference hygrometer at various dew-point temperatures across their range. The more calibration points provided across the range provides a guarantee of accuracy across that range.The higher the dew point rises, the greater the amount of moisture in the air. This directly affects how "comfortable" it will feel outside.
