Bad product
The item was received in bad condition. It’s clear that the wrapping had been opened before it was sent to me. It appears as though someone used it and then rewrapped it—poorly.

Die Funktion ist einfach und gut ablesbar, doch eine Beschreibung ohne deutsch ist schlecht zu gebrauchen. Das gesamte Ergebnis ist aber gut.

This Pin Type Moisture Meter is great! The size is comfortable and with just two features for testing WOOD or BLDG (Building Materials) this is very easy to use without over complicating it. 9V Battery was included!! The owners manual is available online at the manufacturer's website. Humidity will effect results which can vary depending on where you live. Overall, I approve this tool. Great value!!
