Moisture Measurement System
MMS

The Moisture Measurement System (MMS) is a new product for measuring moisture conditions in buildings to aid understanding of how and why damp conditions may prevail.

It combines moisture meter and hygrometer functionality in one state-of-the-art instrument for a complete moisture surveying capability.

The MMS can be used systematically to

(i) Identify the presence of moisture on and below surfaces,
(ii) Measure the relative humidity and temperature of air in built environments and
(iii) Confirm the presence - or otherwise - of condensation on surfaces.

The instrument is compact and simple to use, having a large liquid crystal display and a cluster of just four buttons for selecting the operational modes. It is supplied in a sturdy carry case together with the necessary accessories for a complete moisture survey.

When used as a moisture meter, the MMS has two operational modes known as Search and Measure.

By selecting Search mode and holding the instrument against building elements such as walls, the user obtains a qualitative indication of the moisture level beneath the surface.

By selecting Measure mode and pushing two needle electrodes into the surface of the wood or masonry under investigation, the user can obtain, respectively, the actual moisture content or the material's wood moisture equivalent (WME) value.

The MMS can be used as a hygrometer to measure relative humidity, ambient temperature and dew point. In this way the moisture condition of domestic and commercial environments can be assessed and compared.

The hygrostick® sensor that is supplied with the instrument can also be embedded in solid floors and walls to obtain a material's equilibrium relative humidity (ERH) value. This technique has been widely adopted by the flooring industry to establish if floor screeds and slabs have dried sufficiently prior to laying decorative floor covering. Increasingly, this technique is being used for a wide variety of moisture measuring/monitoring applications in building materials.

For assessing the risk - or confirming the presence - of condensation on surfaces the MMS is used in Condensation mode. When the Surface Temperature Sensor is connected and held against a surface, the MMS displays the difference between the surface's temperature and the dew point together with text messages that confirm whether or not condensation is occurring.
