The Protimeter Moisture Measurement System (MMS) Plus is a complete moisture measurement device for use in many different building related industries. The MMS combines pin type and non-invasive modes of measurement together and a thermo-hygrometer with data storage in one state-of-the-art instrument. The MMS Plus incorporates grains per pound calculation; important when monitoring the drying out of buildings. The MMS Plus is also standard with data download software and a cable for capturing and downloading up to 1000 results to a PC. 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 nylon carry case with zipper together with the necessary accessories for a complete moisture survey.

When used as a moisture meter, the MMS Plus has two operational modes known as Search and Measure. By selecting Search mode and holding the instrument against building materials such as walls, the user obtains a qualitative indication of the moisture level beneath the surface or under a floor covering. By selecting Measure mode and using the standard pin or 5" deep wall probes, the user is able to gather further information at the surface and up to 5" in depth below the surface.

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 (ASTM Standard F-2170-02) to establish if concret floors have dried sufficiently prior to laying a floor covering.

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.
