Michell’s MDM300 portable dew-point hygrometer takes high-speed measurements of moisture in compressed air systems for surgical instruments and breathing air in spot-checks to ensure safety in hospitals.
As with all compressed air systems, keeping moisture levels low is important to avoid corrosion, as well as reducing the risk of bacteria growing.
Bacteria can easily grow in water vapour in compressed air lines, from where they may be released into the air where they can either grow on surfaces or be breathed in and possibly cause infection.
To remove the risk of bacterial growth, it is vital to keep the compressed air at a dew point of less than -46°C.
The MDM300 portable hygrometer provides peace of mind that the moisture level in the compressed air is at, or below, this dew point temperature by enabling spot-checks to be made at critical points in the system.
Each MDM300 portable hygrometer undergoes a 13-point calibration over 10 days before leaving the factory.
The MDM300 is capable of taking measurements on breathing air or surgical air at line pressure with a simple sampling kit – the Medical Air kit. This allows the portable to connect directly to the bulkhead system with a standard 3/8” NGS probe.
Because the MDM300 needs no waiting time between measurements – even to very low dew points – a large number of spot checks can be carried out each day.
The instrument is easy to use, with an intuitive interface which needs the minimum of training to use.
