Sonin 50211 Moisture Meter Question

I picked up a Sonin 50211 moisture meter today for my toolkit, this is the one with the probes at the end of a three foot cord. The probes are a little 'blunt' for poking through linoleum, and I'm considering 'sharpening' them.

I seem to remember reading posts from at least one member saying that they had sharpened the probes on their meter to minimize the size of the test holes. I can't find the post(s) by 'search' at this point.

No problem was caused to the meter by sharpening the probes? Did you simply sharpen the probes by file?

Thanks in advance,


Bob and Nancy

I sharpened mine with a file. The points make a tiny hole, you just have to press through the vinyl to check the wood subfloor, not deep. On the perimeter I put it up against that rubber molding and a fake joint in the vinyl so the hole is hard to see, almost disappears. I try to use the same holes each time I inspect for leaks but they can be hard to find (which is good).

You would want to try to minimize probing around the entrance door, bath and shower, and kitchen, places that may normally see a wet floor. The vinyl is a waterproof cover for the subfloor so you don't want to leave holes in it.

The most likely leak areas are under pano windows, subfloor next to rear bumper storage, hinge side of entrance door, under awning support brackets, and where water runoff from the roof concentrates.
