Flagship Dewpoint and Temperature Transmitter DMT340 series

for Demanding Low Humidity Conditions

Condensation-resistant Vaisala Dewpoint Transmitter DMT340 is designed for industrial low-humidity applications such as industrial drying, compressed air systems, semiconductor industry, dry rooms, baking ovens, and metal heat treatment to provide accurate and reliable measurement.

What is Dewpoint?

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.
