The MDM50 Hygrometer has been designed to make high-speed spot checks of the dew point in air and gases to -50°C 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.
