Why do inspectors need moisture meters?
Hidden moisture in homes remains one of the most significant caused of building damage. Since the home inspection is not a destructive inspection moisture can easily go unnoticed. A good moisture meter can assist with identifying potential problem areas. While the inspector is not necessarily interested in obtaining an exact moisture content (MC) reading, relative moisture content (RMC) readings are sufficient to identify areas requiring further investigation.
What does this meter do?
The BI2200 Building Inspection Moisture Meter is a moisture meter designed specifically for use by building and home inspectors. This meter provides comparative and relative moisture content readings for common building materials. It is a pinless meter, which means that it uses electromagnetic waves to obtain the reading and is therefore a non-destructive / non-invasive meter. The BI2200 Building Inspection Moisture Meter can be used to establish a baseline at a known ‘dry’ area which can then be used to identify and compare to areas and conditions with an elevated moisture content.
Why do we think this is a good meter?
The BI2200 can take relative reading for a number of materials including drywall, plaster, tile, shingles, stucco, concrete and linoleum.
Given the compact, lightweight design, and the one-handed operation, the BI2200 can be used in tight spots. The meter holds its reading once the measure is taken which means that the meter can be used in confined spaces where a straight line of sight to the meter is not possible. A non-abrasive pad protects the sensor on rough areas and prevents damage to the material being measured.
The moisture meter is approximately 4.5″ x 2.75″ x 1″ in size and weighs .37 lbs. It is powered by a 9 volt battery (included) and has a 60 second automatic power shut down to extend battery life. The meter is controlled by means of a simple two button control. It has a measurement depth of 3/4″ and the moisture assessment criteria for this meter is ~5-32% (relative). The meter typically comes with a 1 year warranty and a carry case and belt clip.
What are the drawbacks of this meter?
The first drawback is that this is not an inexpensive moisture meter. It is however also not one of the most expensive moisture meters on the market. The second drawback is that it only provides a ‘relative’ reading and will not provide exact humidity % readings. Few, if any, home inspectors will however require exact readings during a typical inspection, and if this is you, another meter might be a better option (see below). A few owners of the meter mentioned that the 60 second auto shut-off can be troublesome if you need more than 60 seconds to take a picture of the meter with a reading in place.
Who would benefit from owning this meter?
This meter is ideal for home, building and mold inspectors looking for a reliable tool capable of obtaining relative moisture readings. It is easy to use, holds up well on site and provides the information needed to guide your investigations.
