Main highlights

The BM31 not only allows the quick indication of various near-surface material moisture values, it is also particularly suitable for preliminary testing of the readiness of building materials for CM measurements.
The BM31 is not only ready for immediate use, during measurement it also impresses with fast response times and at the push of a button shows the user helpful additional information such as minimum and maximum values in addition to the current real-time measured value on the easy-to-read back-lit display. Additionally, the momentarily measured value can be recorded via the hold function.
The BM31 is an electronic moisture indicator that allows you to quickly and easily detect moisture near the surface in various materials and locate moisture distributions in the wall, floor or ceiling.
Practical advantages: Development, design, production: 100% Trotec. Fast and non-damaging indication of moisture distribution in areas close to the surface. Useful pre-test device for CM measurements. Minimum value, maximum value and hold function. Automatic function and battery test. Can be used immediately. Optimum Can be used immediately. Illuminated display. Automatic switch-off. Practical German industrial design - Registered Design
Due to the dielectric measurement process, moisture indication takes place in a completely non-destructive manner and no electrodes or probes need to be inserted into the material to be measured.

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.
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. 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 BM31WP and make this meter a valuable tool.

Main highlights

Note: Since the moisture content of the hand affects the measurement results, the smaller the contact area between the hand and the device (the further the distance to the ball head), the closer to the true value. Tadeto offers 1 year quality support, so let us know if you need help.
Non-slip and ergonomic design: the moisture meter made of soft TPE rubber is more resistant to falls than other moisture meters and sits better in the hand during operation and use. It can be easily operated with one hand. 1/4" screw hole on the back to combine different tools to reach hard-to-measure areas. Thanks to the compact size, the hygrometer can also be easily transported in a bag.
Improved HD colour screen: the backlit LCD colour display of the moisture meter has been equipped with a consistently higher brightness, regardless of the light intensity, the measurements can be read in a range of 360° without blind spots. Featuring a 3-color bar chart, "DRY", "RISK" and "WET" status in "Green", "Yellow" and "Red". With hold function, max/min display, optical and acoustic alarms (alarm range can be set manually).
Automatic calibration: the wall moisture meter can be automatically calibrated and only takes 3 seconds to start measuring after switching on and pressing "MEAS". Recalibration is required every time you change the measurement environment. Hold the bottom of the wall moisture meter firmly to prevent moisture on your hands from affecting the results. Please note: metal cannot be measured.
Accurate and non-destructive measurement: the moisture meter uses a high-precision alloy probe and a powerful processing chip to provide accurate and reliable results. By using a non-invasive measurement method that does not damage the material surface, the extended handle and probe easily cover a variety of narrow and difficult areas and measure at a depth of up to 40 mm with a measuring range of 0-100.
