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. Addition of more water vapor results in condensation.



Measuring dew point in industrial settings is critical to ensuring that sensitive equipment does not undergo corrosive damage and the quality of end products is preserved



We distribute a range of stable and reliable dew point transmitters both for OEM configurations as well as for end users: dewpoint for compressed air, dewpoint for air dryer, dewpoint for hopper
