Because it has its own self-contained sampling system, setting up the MDM50 involves simply connecting the hose to the sample point: there are no extra sample conditioning add-ons to purchase or to carry around. The integral sampling system allows for measurements of dew point to be made at pressure, up to 20 barg, with an option available to measure up to 300 barg. The integrated filter removes particulates down to 0.3μm which provides 99.5% protection to the sensor.
A long battery life is essential for making measurements in the field, especially in locations where there is limited access to charging points, so the MDM50 portable hygrometer has an operation time of 16 hours on one full charge. This means users have the confidence that they can work all day without having to stop taking measurements for charging. The universal charger fits neatly into the case when not in use to make sure it’s always handy.
The fast-responding polymer moisture sensor of the MDM50 gives rapid dew-point measurements in compressed air – T95 to -35°C from ambient typically in less than 5 minutes. The sensing element is highly stable, resistant to contamination and, along with the robust and sturdy case, this means the hygrometer is well-suited to the often tough conditions in industrial applications.
As well as dew point in compressed/instrument-air dryers, typical applications for the MDM50 include moisture measurements in medical gases, polymer chip and the output from refrigerated dryers
