Someone came to test my flat walls for damp.
He had an analog meter with a finger moving around a clock face type
dial. This meter had an extensible probe on a lead.
He said he couldn't check behind the back partition of my fitted
cupboards because the probe couldn't sense the wall behind the
composite material.
I decided to get my own meter and drill a hole to allow the probe
through to the masonry wall.
First off, I could mainly find digital meters online. Even the
"analog" ones seemed to have a digital display and none of them had an extensible probe, only a couple of short spikes coming out of the head
of the meter.
I don't want to go too expensive for a one off job, but any advice on
getting a suitable meter would be appreciated.
Those meters are for only checking the moisture content of (cut) timber
and are misused by the charlatans testing for rising damp. They are
basically resistance meters and will always indicate rising damp in a
dry wall where salts have come out of the mortar or plaster, or
condensation on the surface of the wall.
