About this deal

Press the meter up against the wall and apply a small amount of pressure. Hold it for several seconds and wait for the value to stabilise on the meter’s reading screen. Put differently, if the reference scale shows a reading of 20%, it does not mean that 20% of the dry weight of the tested material is water. Instead, it just means that the moisture content of the material represents 20% of the reference scale.

It has a measuring range of 4% to 80%. This device is powered by three 1.5-volt AAA batteries which come with this product. Pros Scenarios in which a pinless moisture meter is best used include for testing surfaces which are large and flat including a room’s entire floor. Measure Moisture Level, Spot Hidden Damage】AZUNO moisture meter is an invaluable tool for homeowners, woodworkers, floor installers, and inspectors. Trusted by both homeowners and professionals alike, moisture meters are relied upon to identify hidden problems, helping to prevent costly repairs. This versatile product has a 3-in-1 application as it can test sunlight, moisture and pH levels. The latter feature will allow you to figure out how much sunlight is reaching a given area of your soil.

This meter is the first pinless product in this section. This product has a range of unique features and comes with the various benefits that a pinless meter offers including speed. This product is good for going over delicate surfaces. It's small and ergonomic. Your meter may provide you with precise, quantitative results but without a chart to reference, you may not know what the numbers it's showing actually means. Wood and lumber should have moisture levels of 6% to 8% for internal materials while external wood and lumber should have levels of 9% to 14%. Does not provide as wide a range of measurements as compared to some of the other products on this list. However, if you want to use a moisture meter as an aid to diagnosis of damp in masonry or plaster, remember that it is not calibrated for that material. It cannot be so because the wide variety of densities and materials is just too vast. Natural materials like stone can vary within a wall too. A wall is made up of the mortar, the masonry units and the plaster. Any profiling must be done in each separately; never mixed. You cannot compare qualitative readings from different materials. You must not rely on the meter to take quantitative readings. The numbers, colours or sounds refer to ‘relative’ amounts now. You can tell where moisture is present and how much more damp or, much less damp parts of a wall are. The readings are now qualitative. This is important! It is also very useful to a surveyor. The first step to solving any moisture problem in materials is to correctly identify the location and extent of the issue. The Dryzone Moisture Meter gives a reliable and accurate picture of the extent of the damp issues in wood and masonry that a visual inspection cannot match.

The top layers can be bone dry and show how values on the moisture meters but since concrete dries from the top to the bottom, deeper layers can be saturated yet still not detected by the instrument.

A pin moisture meter uses pins instead of a pad (that a pinless meter uses). Other differences between these two types include that a pin meter can leave holes in the surface it is measuring, pin meters also require different setting adjustments than a pinless device and pin moisture meters also work slower than pinless meters. This moisture meter has audible alerts which change their frequency as you go across higher concentrations of moisture. It also comes with varying modes. Unlike most moisture meters, this device has an LED screen. Second, because it also has many applications and can be used for different purposes with different humidity tolerances. For example, we know that “normal” for drywall is dry. So if you want to use a drywall reference scale, start by applying the moisture meter to drywall that you know for sure is dry. Record the reading you get and use this as a baseline. Your screen will then give you either a percentage or a reference reading. Take note of the reading.

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.

What does moisture content mean?

Our step by step approach to using a moisture meter is broken down based on type but these exact steps may need to vary depending on the device in question and which material is being tested. We will discuss these types of moisture meters in more detail in the next section. Using a Pin Moisture Meter But be careful here, the values showing on a reference scale do not represent the moisture content of the material under test. Instead, these are just estimates where high values mean high moisture levels and low values mean low moisture levels. This product is a low-cost pin-type meter with a wide and accurate measuring range. It is good for making fast moisture measurements of wood materials. It is small and particularly lightweight. This device is simple to operate and features various display icons that show the levels of moisture present inside the tested surface. Its tech features include an audible alert and a data freeze application. It comes with a small display. This meter from Extech is the first all-in-one product to feature in this section. This product is lightweight and comes with the benefits of both a pin and pinless moisture meter.

With that in mind, and similarly to what we said about drywall, concrete must remain dry and damp free. So all we can say here in that a normal moisture meter reading for concrete needs to remain low.Repeat this process several times by measuring different areas of the same surface. Find the average reading from all of the measurements undertaken. This product is another pinless moisture meter. It has a great measuring range and an intelligent shut-off feature. Other benefits include its high levels of accuracy. This product is ideal for measuring delicate surfaces since it is pinless. It is small and relatively lightweight. When used properly, electronic moisture meters are an essential tool for any surveyor involved in the diagnosis of damp and moisture related problems in buildings. It has a large LCD display that’s easy to read. Its measuring range for wood is 2% to 70%. It is powered by three AAA batteries which come with the device. Pros A moisture meter is a device used to measure the levels of moisture present in a building. They are often used to measure moisture levels in walls. Moisture meters can either work as conductivity meters or as capacitance meters.
