Questions & Answers

Will this meter measure moosture in a concrete slab?

I have hairline cracks in my foundation. And i want to measure the moisture in the slab
Asked by: Billy
The manual makes no mention of measurements in concrete because this is a Pin-type meter. The pins need to be pushed into the material being measured, and you can't push the pins into concrete. Therefore, moisture "in" the slab cannot be measured. But if there is standing water on top of the slab, the meter will detect it, but in that case you could see and feel the water anyhow. If you can get the pins into your hairline cracks, you might be able to get a reading, but only as deep as the pins (about 1/3 of an inch). To get an accurate moisture measurement "in" concrete, foundation crews drill out a core plug about 1" in diameter and send it to a facility for analysis.

Will this device give me a moisture reading in my stucco on the front of my house if I drill 2 small holes w/masonry bit

Asked by: George
You may get a reading, but its value is questionable because readings should always be taken at several different spots in the area. The reading you get from your 2 small holes may not be indicative of the moisture content elsewhere.

Pin-Type Digital Moisture Meter with LCD Display is rated 4.4 out of 5 by 43.

I use if for woodworking, especially for drying green wood for turning. Pins on top leave virtually no holes (for a surface reading). The cover (top) is pretty cheesy, which cost it 1 star. I wish the cover was permanently attached in some way to avoid loosing it.

For the money, an excellent device for tracking moisture in wood, dry wall, etc. Seems to be accurate and reliable. Just wish there was better guidance on when to use the wood/brick button, but I don't think it matters much for the overall operation.

Rated 5 out of 5 by from Easy to use I've used this a couple of times now and it's so easy. All you do is turn it on, push the pins into the wood, and read the results. It includes a test to confirm it's calibrated correctly and mine was spot on right out of the box. My neighbor has already asked to borrow it when he goes to the lumber mill. I highly recommend this product.

Calibrates consistently to amount stated in directions, and gives consistent readings to a range of boards with varying moisture content. I doubt there's another instrument that can approach the consistency of this meter for the price. Obviously I recommend it from the two months I've had and used the meter. Arrived one day earlier than they estimated.

Rated 4 out of 5 by from Simple but functional Last year we felled our mulberry tree. I kept the thicker parts for later use because mulberry wood has a nice yellowish color. To see if the wood was dry enough to use I needed a moisture meter. I checked various models and based on the reviews and price, Out of the box I used it on all sorts of wood, just for testing. I have no way to check the accuracy of the readings but I think the scale is quite right. It went from 8% for my workbench to 45% for wood I brought in from outside. All in all I'm satisfied with the performance. The only negative aspect is the two pinholes from the needles but that I knew already before I bought it. So I use a spot that has to be worked on.
