Online Dew Point Meter

 Online Dew Point Meter

The exact monitoring of dew point temperature in compressed air systems, dryers for plastic and other industrial processes is becoming increasingly more important.

The EE 375 is designed for measurement of low dew points in OEM application down to -60C (-80C)

The core of the transmitter is the monolithic measurement cell type HMC01 developed by E+E Electronic in thin- film technology.

An autocalibration procedure which is integrated in the device and years of experience in low humidity adjustment make an accuracy of <2C Td (+-3.6F Td) possible.

The transmitter has one analogue output for dew point, frost point or ppm volume concentration.
