    Hello Just, this device measures the moisture content in wood at a depth of 0.3" (8mm) on Pin Mode and up to 1" (25mm) on Pinless Mode. When measuring wood siding on Pinless Mode, please ensure there are no metallic materials inside or behind the wood.

            Do you need to drill holes in concrete to test it
            ByOct 4, 2022
            1 Answer | 
            Answer This Question

            Hello Linus, please note that the pinless function of moisture meters are considered non-invasive, and thus do not require any drilling into the material you are measuring. The pin function does not require drilling either but may leave marks on the surface you are trying to measure.

                Nice little unit
                This Reed Instruments Pin/Pinless Dual Moisture Meter is my first moisture meter, so I can’t compare to any other models. What I can tell you is I am very happy with it and it seems to be well made. The pinless mode is very interesting, it’s like magic taking readings without sticking the probes in the material to be tested. Also as an added bonus it can take a pinless reading in concrete up to 1 inch deep!
