The
MDM50 Hygrometer has been designed to make high-speed spot checks of
the dew point in air and gases to -50°C (–58°F) dew point as simple as
possible. This completely self-contained instrument weighs only 4kg and
is delivered ready to use. Simply connect your sample gas to the Quick
Connect fittings, turn on the instrument, and it will automatically
begin to measure the dew point of the applied sample.
