When burning wood, it is important to know the wood moisture content. If the wood moisture content during combustion is too high, the water must first be heated and evaporated. This results in lower flame temperatures and smoldering gases. In addition, it can lead to incomplete burning of the wood. In summary, too high wood moisture results in poor efficiency, pollutants and also odor emissions. To ensure this, the Bluetooth construction moisture meter is used. With the Bluetooth wood humidity meter, up to 44 different types of wood can be checked for their moisture content. These include 36 deciduous and 8 conifers, such as beech, spruce, pine and maple. The measured value can be up to 150% humidity in relation to the dry mass. In order to obtain the most precise measurement bite, the Bluetooth construction moisture meter has an automatic as well as manual temperature compensation between -20 to +50 °C. In order to carry out a measurement, first strike a pair of measuring tips into the wood using the electrode with the Bluetooth construction moisture meter. Two different pairs of measuring tips are available with the Bluetooth construction moisture meter. With the pair of needles 45 x Ø3,05 mm can be inserted into the wood up to a depth of 30 mm. The 165 x Ø2,85 mm pair of needle allows the deflection up to a depth of 150 mm. Then the wood type to be measured is selected via an Android or iOS device and the measurement is started. After a few seconds, the current measured value is displayed. The connection between the Bluetooth construction moisture meter and the mobile end device is via a Bluetooth 4.0 interface. After a measurement, the measured value can be stored by the Bluetooth wood humidity meter on the mobile device. The data can be exported in CSV and PDF format. A 9 V DC power supply unit is used for the power supply of the Bluetooth construction moisture meter. For mobile use, the Bluetooth construction moisture meter can be operated with a 9 V block battery.This text is machine translated.
