There are different models of moisture meters available in the market and whichever model you use, it becomes important to understand their working and the information you can get from them. These details can enable you to get the most out of the device, regardless of the model you are opting for.

Which meter to use? In general, this device is divided into two types and they are invasive and non-invasive moisture meters. The former is otherwise called as pin-type or penetrating meters and they operate based on the principle called conductivity or electrical resistance. Here, the pair of pins should be inserted on the material on which the moisture content should be measured. As conductivity differs as per the level of humidity present in the material, it will be possible to quantify the moisture level. This type is generally called as wood meters because their main purpose is for identifying the level of moisture in wood. Some models will also have a drywall setting or gypsum that uses different scales of measurement.

The latter type non-invasive meters are otherwise called as pinless or scan-type or non-penetrating ...
... meters. Under this type, the two main technologies, namely; Electronic capacitance or impedance technology and radio frequency technology are used. The machines working based on the former technology, use a set of rubbery pads that are placed in contact with the surface of the material that is being tested, while in the case of the machines with the latter technology, a radio frequency signal is sent into the materials with the help of a smooth plastic pad. Both these technologies give the details about the level of moisture with figure-based representations on the basis of modification of motions produced from the electronics.

When you compare the above-mentioned types, you can come to a conclusion that a non-invasive moisture meter can the best as it will not make any hole in the material that is being tested. But, this type has two main disadvantages. One is that the humidity present in the surface can give a false report and the second is that reading depth is limited.

Not only for wood, these meters will be useful for agriculturists too, as they can measure the wetness in soil. Some crops grow only when the wetness in the soil is limited, while some might need extra wetness. These people have the option of using a digital moisture meter, which will give the result of the wetness in the soil in digits.

The digital moisture meter can be a great tool for farmers to identify the water content in the soil for each plantation and can take appropriate action to ensure proper growth of the crop.
