BM31 provides you with an effective, reliable and non-destructive means of locating the spread of moisture up to a depth of 4cm (1.6”)* below the surface of any walls or floors you wish to check.

The BM31 is a dielectric measuring device which can quickly determine and measure the moisture content of areas below the surface of floors, walls or ceilings without so much as scratching the surface that is being tested. No pins, no electrodes, no nothing. This makes the BM31 ideal for carrying out preliminary testing to ascertain whether the time is right to perform further tests which would then provide the user with conclusive evidence.

Although the ergonomically-formed BM31 is one of the low-price entry models, it is nonetheless built to last. The BM31 has a number of extremely useful features like a minimum and a maximum function which provides you with the highest and the lowest readings and a hold function which allows you to freeze the last value you have taken so that you can decide when you would like to read it off the unit’s crisp, clear backlit display.

In addition to these features, the BM 31 also has clearly-arranged, easy-to-use soft touch keys and an auto power off and a battery testing function to ensure that you have enough power to carry out your measurements when and where you need it.
