Michell Instruments has introduced the new MDM50 portable hygrometer, which enables quick and easy spot checks of dew point or moisture content down to -50°C dew point.
Since it has its own self-contained sampling system, setting up the MDM50 simply involves 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 0,3 m, which provides 99,5% protection to the sensor.
The fast-responding polymer moisture sensor of the MDM50 gives rapid dew-point measurements in compressed air, typically in less than 5 minutes. The sensing element is highly stable, resistant to contamination, and along with the robust carrying case, this means the hygrometer is well suited to the tough conditions in industrial applications.
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. A universal charger is included with the unit and stored in the case.
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.

Maintenance, Test & Measurement, Calibration
Microdieseling is a pressure-induced thermal degradation mechanism in which entrained air bubbles are compressed so rapidly that the surrounding oil ignites, producing soot, varnish and sludge. WearCheck explains how it happens, why the damage varies, and how oil analysis detects it.
