BM12 Moisture Meter


With the very easy operable BM12 you measure wood and building moisture in seconds. The changeable puncture seal measurement pins ensure a solid connection to the bulk source and thus precise measurement results. With two choosable measuring modes you can set the BM12 either on wood moisture determination of timber and firewood or on building moisture determination on soft building materials like plaster, stucco or screed.
Besides the Material moisture this instrument determines the ambient temperature as well, which can be read off optionally in °C or °F.
The instrument also disposes about a long life battery duration through the automatic switch off. So it turns off after not using it for 2 minutes.
There is a callibration curve for wood moisture determination of common wood in Europe intergrated in this instrument, therefore no further adjustments are necessary for the determination of wood moisture content.

Simple device ...
Activated the supplied batteries ... “Stabbed” the wall, gently, with the prongs ... instant reading 13 - 14%. Need to figure if that is good or bad! Recommend device to anyone. Read more

Perfect for the price
Easy to use, simple to understand... used to locate source of damp in ceiling... as good, if not better, than something ten times its price. Read more

Neat product which works as designed, sold at a very reasonable price
a very good tool, does exactly what it says on the box. It is petite useful and well designed. Like someone else said I too would prefer a more readily available battery, but this would probably mean a larger package. Read more

Does The Job
I bought this item as a means of testing when the plaster had dried sufficiently to paint in a house renovation project. You have to realise that this isnt a top of the range meter which could cost you an arm and a leg, it has after all only cost you around £11.99. However, for the job I wanted it for it was perfect and I dare say punches above it's weight. It's robust and told me exactly what I needed to know as my walls dried out. Very pleased with it.

moisture meter for my logs
Seems to work fine, smaller than I imagined and not a great fan of those really small batterys prefer a couple of triple A's but that's just my personal preference. Read more

This damp meter replaces an old one.
The old one was twenty times the price of this one at least. This one is quick and simple to use , it has two main functions as in timber or masonry plus it has a thermometer built in which gives more of an ambient reading. Nice little cover for the two prongy type electrodes. It seems very accurate too which I.s a bonus. Read more

I made the right choice
well made, easy to use, i think the digital readout easer to read than the graph one. I have used it to damp test my motorhome at the same time as repairer was using his meter, our readings matched so mine is as accurate as a professionals. yes I recommend and I would buy again. Read more
