Product Information

Ermenrich Wett MW40 Moisture Detector

The Ermenrich Wett MW40 Moisture Detector is a device used to measure moisture levels in wood. It features a moisture scale, wood density indication, and a current moisture value display. The device also has a HOLD function that allows users to hold the current measurement on the screen. The MW40 has a DENSITY button that is used to select the wood density grade and a MODE button that is used to select the measuring mode. The device is powered by batteries and has a low battery indicator. It also has an alert setting function that allows users to set alerts for certain moisture levels. The MW40 is designed for indoor use only and should be kept away from children.

Product Usage Instructions

Carefully read the safety instructions and user manual before using the product.
Turn on the device using the POWER button.
Select the measuring mode using the MODE button. The device has four measuring modes: wall, masonry, softwood, and hardwood.
If applicable, select the wood density grade using the DENSITY button. The MW40 has a table of wood absolute dry density for reference.
Place the device up to the sample so that the sensor (12) touches it.
The current moisture value will be displayed on the screen. Use the HOLD button (9) to hold the current measurement on the screen. The HOLD icon will be displayed.
To set an alert for a certain moisture level, turn on the device and press the SET button (8). The digit that is to be set will blink. Use the SET button and DENSITY button (7)/(11) to
adjust the value of the blinking digit. Press and hold the HOLD button (9) for 3 seconds to confirm the setting. To cancel the alert setting, press and hold the SET button (8) for 3

Note!

If the wood of the measured sample is not listed in the table above, use the following equation to calculate the absolute dry density. Density = (100 x weight / volume) / (100 + moisture content of the wood)
Weight unit of measurement: gram
Volume unit of measurement: cm³
Select grade “1” for densities below 0.25g/cm³.
