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.
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.

With just a single control button, you can turn on the BM18 and make all the settings. To choose between the measurement modes wood moisture, building moisture and temperature in °C or °F, press and hold the button for about 3 seconds.
When not in use, the device automatically shuts off after 30 seconds to ensure a long battery life. A too weak battery voltage is indicated in good time in the easy-to-read display.
The BM18 also has a calibration curve for the wood types common in Europe for wood moisture measurement. No further settings are necessary to determine the wood moisture content.
For temperature measurements, the humidity meter displays the current ambient temperature. For moisture measurements, press the puncture measuring pins a few millimetres into the material. So you get precise and fast results. When taking measurements in dark environments, press the button to turn on the backlight. This automatically goes out after 3 seconds.
Advantages for practice: wood moisture and material moisture measurement with one device / with protective cap / can be used immediately / display of the ambient temperature optionally in °C or °F / calibration curve for common types of wood / optimal value for money / including LED humidity indicator / easy to use with just one button / easy to change puncture steel measuring pins / direct measurement value display in vol% / mode mode freedom switch switch Battery status indicator/automatic switch-off

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.
