Here at ETI we manufacture a range of portable, pin-type (resistance) moisture meters for both the professional and the craftsman. Pin-type moisture meters are acknowledged as a reliable way to obtain percentage moisture readings in a wide range of building materials. The relationship between moisture content and electrical resistance provides consistent and accurate results over the range of 4% to the fibre saturation point, which is approximately 30%, dependent on the material.
Some moisture is unavoidable and may even be necessary in certain building materials, but too much moisture can cause mold, decay and other problems. Our moisture meters are cost-effective instruments that can easily determine moisture levels – allowing the user to diagnose problems and make informed decisions with regard to remedial actions.
Problems in Measuring Moisture
The main problems arise from the ‘structure’ of the material being tested, in particular, the presence of other conductive material that can affect the reading.
Therefore when measuring the moisture content of a material it is important to appreciate a number of factors:
- Surrounding environment
- Density of the material
- Grain size or direction
- Ability of a material to absorb moisture
Why Measure Moisture in Floors & Walls?
Many of today’s flooring materials use water-based adhesives, which are more likely to fail than the older, traditional, solvent-based adhesives. Moisture can cause laminates to fail, tiles to lift and hardwood floors to warp or split. A newly poured concrete floor slab is usually the slowest-drying element of a building. Therefore it is important to measure the moisture content accurately to ensure a successful floor. Measuring the moisture content of walls is a traditional method for locating damp and other related problems, i.e. damaged pipework, breached damp-proof courses etc. It is important to ascertain the cause of the dampness, i.e. rising damp, penetrating damp or condensation before any remedial action is undertaken.
The 7250 is a compact, general purpose moisture meter designed specifically for building professionals and tradesmen to check the moisture content in a variety of construction materials. The moisture meter features a 20-LED bar graph within the keypad which displays current moisture levels; green for ‘OK’, amber for ‘WARNING’ or red for ‘DAMP’. The digital meter incorporates five scales of measurement. Read more here.
The 7000 is a compact, general purpose moisture meter designed specifically for building professionals and tradesmen to check the moisture content in a variety of construction materials for moisture content diagnosis. The 7000 also features the same 20-LED bar graph indicator as the 7250, however the 7000 has interchangeable 2-pin probes. This allows you to use the General Purpose Probe, Heavy Duty Hammer Probe or the Deep Wall Probe. Read more here.
Designed specifically for the construction industry and based around the 7000 moisture meter, this moisture meter kit is a complete solution for measuring the moisture and dampness in a variety of building materials. This kit represents excellent value for money as it is supplied in a FREE carrying case and includes a two-pin probe, two packs of pins and a FREE protective boot. Read more here.
