Main highlights

The appSensor BM31WP is an electronic humidity indicator which, in combination with the MultiMeasure mobile app, enables non-destructive capacitive moisture determination in areas near the surface of the wall, floor or ceiling.
The BM31WP meter is ready to use, can be easily connected to the app and allows you to quickly and easily locate near-surface moisture distributions in the wall, floor or ceiling - and absolutely non-destructive.
Or use the measured values in combination for differentiated analyses directly on site. Useful additional features such as the alarm function, the export of moisture readings into advanced analysis software and the creation of a report round off the universal application possibilities of the BM31WP and make this meter a valuable tool in the field of building diagnostic tasks.
Not only is the quick indication of a wide range of material moisture values close to the surface possible with the BM31WP, this appSensor is also particularly suitable for pre-testing the proof of building materials for CM measurements.
Compared to non-app-supported moisture meters, users of the BM31WP benefit from numerous additional advantages in terms of flexibility, analysis functions, data control and documentation due to the clever combination of appSensor and accompanying free Multimeasure Mobile app. Compare different moisture measurements of an object directly in the app, which were created at different times.
