Moisture Meter ?
brother and I started our water damage restoration firm in 1982, we have dried
over three thousand homes. Practically
every job we have had, we would always hear the same question from our
customers “How can you tell my walls are wet, they look fine to me?” I then introduce to them the moisture meter,
and they were all fascinated with it and how it works.
We use two
types of moisture meters - Penetrating and Non-Penetrating
moisture meters use two sharp pins or probes that are inserted into a material
or structural element which you suspect is wet. An electrical current passes
from one pin to the other and the resistance is measured and that resistance
determines the amount of moisture within the material. This type of meter is great for determining
the moisture content in wood and for checking carpeting for moisture as well.
moisture meters do not use pins, but rather sensors. These types of sensors
work by sending an electronic signal into the material and measures power loss. The benefit of using this type of meter is
that you do not have to put holes into your drywall to determine if it’s wet or not. Also you can check large areas
quickly to determine where the moisture is located.
How we do
it at Puritan
Flood Restoration we always check the drywall after a flood using a non-penetrating
moisture meter. The Technician will find
a known dry area in an undamaged area of the home or business. Then they will
use that reading to establish a “drying standard”. This drying standard is what the technician
will consider dry. They will then use
that reading as their “drying goal”. The Technicians then sets up our drying equipment
to dry those areas until the walls reach our drying goal.
meters run from inexpensive to very expensive. For a water damage restoration
firm like ours, a more expensive one is necessary. But for the home owner an inexpensive one will
work just fine. The inexpensive ones
will usually be a penetrating moisture meter that will show you whether something
is wet or dry.....................Good Luck and Stay Dry!
