Dewpoint hygrometer

The Michell Instruments MDM300 advanced dewpoint hygrometer can be used to accurately measure dewpoints as low as -70 °C in less than 10 minutes.

The fast response does not rely on the sensor being dried by a desiccant, which means that every measurement is fast allowing for many more measurements to be taken each day.

Efficient nickel metal hydride batteries and power management circuitry provide the user with 48 hours of use between charges. In addition, a flat battery can be recharged to 90% of its full potential in just 20 minutes, thanks to the intelligent charger.

With its Bluetooth connection, the MDM300 connects wirelessly to a PC and set-up of the instrument and downloading of logged data is quick and simple.

A number of cost-effective and easily portable sampling systems are available for the MDM300 to ensure accurate measurements and help prolong the life of the sensor. These range from simple fixed orifices for low pressure measurement all the way to high-quality configurable sampling systems for pressures up to 400 barg, designed for use in natural gas and other demanding process environments.

To maximise flexibility, measurements can be taken by means of external sensors which are easily connected to the MDM300. These sensors can be used to display dewpoint, pressure or temperature or can be used to provide pressure and temperature compensation to the displayed moisture parameters.
