The baseline value can also be considered as a goal to achieve as you begin to dry out the infected surfaces. Incredibly accurate (despite an unspecified accuracy by the manufacturer); ideal for precision work
Second, because it also has many applications and can be used for different purposes with different humidity tolerances. Align the pins perpendicular to the surface before pushing them directly in as far as they can go. Hold the pins in this position. There are many different brands and models of moisture meters available so you’ll need to carefully consider which one is the right one for you.
These devices also help you burn firewood safely. There are some risks that come with burning firewood that is too wet or too dry, as you’ll see below.
There are different types of drywall. Greenboard is moisture-resistant and created by surrounding the gypsum drywall core with a moisture-resistant covering. You can also buy fire-resistant drywall and drywall that’s flexible enough to create curved walls or ceilings. Do Pinless Moisture Meters Work on Drywall?
Moisture Meters Compared
The accuracy of a moisture meter varies depending on the material you are testing, the calibration of the meter, the type of moisture meter, the procedures used during the test, and the meter’s functionality, which can vary based on upkeep and maintenance of the unit. With the use of its pins, it offers a measuring range of 5-50% for wood surfaces and 1.5-33% for building materials. With the pinless sensor, the range for both types of surfaces increases to 0-99.9%. It is powered by a single battery that comes with the product. Pros
Repeat this process several times on other areas of the surface. This will maximise the accuracy of your measurements by taking multiple readings and allowing you to find the average. This is best done on wood surfaces. If for example we have a wall with some damp stains. They could be patchy and ill-defined. In the video Bryan mentions ‘profiling’ the wall so that we get a better idea of the distribution of the moisture in it. This is great because in general the higher readings will be nearer the source of the moisture and the lesser readings well, further away. This is basic but very useful as an aid. Visual evidence is important, but the meter may sometimes show that the source of moisture doesn’t follow the stain pattern – very useful. Profiling is done to obtain the distribution and then compare that to what the surveyor sees; the type of construction; location; topography and other factors. A diagnosis can then be reached and will normally be accurate if, the surveyor has used his skill, judgement and equipment correctly. He should know how to use a moisture meter properly.This meter may be used to detect ambient temperatures. It’s small, ergonomic and easy to utilise. It has accurate measurements for two different wood groups and five groups of building materials. This device has an auto shut down feature which works following five minutes of inactivity.

Screed: Before applying a floor finish, the screed must be dried to an acceptable level, and it is the contractor’s responsibility to ensure that an accurate moisture assessment has been performed before the final floor finish is put into place. There are a few different methods used for determining moisture levels in screed. This includes the air hygrometer test (time consuming), which is the recommended testing found in BS Standards cited above (8201:2011 and 8203:2001+A:2009), the calcium carbide test (destructive) and the Tramex meter test (non-destructive).
