Moisture Meter is used to measure the water content/percentage of water in a given substance e.g. seeds, food products and any others. It estimates the moisture content of certain textile materials by utilizing the relationship which exists between their moisture condition and Electrical Resistivity.
The Moisture Meters depend on the Conductivity Measurements, Capacitance Measurement and Electrical Resistivity. These meters are equipped with Sensors known as Transducers which help in converting onekind of energy into another type of energy. A novel Moisture Meter sensor depends on the following principle.
Frequency measurement; meter operates on the principle of non destructive measurement
Time domain measurement; meter works on the principle of change in the time duration of passage of the pulse through the material.
These Moisture meters provide non-destructive measurement content in soap, soap cake, paper, cement and food industries such as-biscuits, chocolates sugar syrups i.e. no damage to material.
Here are some different types of Moisture Meters which are used for different purposes.
1、Moisture Meter for Wood
The Wood Moisture Meter works on the principle that the wood resistance decreases, as the moisture content in the wood increases. The decrease in the resistance is converted into digital data and the moisture meter displays the percentage of water in the wood. The Moisture Meter consists of two electrodes, which are inserted into the wood, to find out the resistance between them and hence its moisture content.
2、Moisture Meter for Concrete
Concrete Moisture Meters were introduced to check out the moisture content in the concrete slabs that are used in construction. Their principal of working and finding out the moisture content is same as that of the Wood Moisture Meter. The resistance between their electrodes is checked out here too, to find out the moisture content in the concrete. However, they significantly differ in their moisture detection and moisture analysis methods, from the Wood Moisture Meters. They can measure moisture at a depth of 1 inch from the moisture surface. This is required because people working in the field need to know the moisture content at the depths of the concrete slab, to analyze the construction.
3、Moisture Meter for Soil
This moisture analysis is required to find out if the plants in your garden would require watering or not. It may happen that because of rain, the moisture content in the soil is already sufficient and your plants do not need any more water, for a considerable amount of time. Under such cases, a Soil Moisture Meter can be used for the moisture detection and moisture analysis in the soil, to find out regularly, if the plants require any additional watering. If it rains regularly and your plants are getting over watered, then the moisture analysis can help you in determining if you need to take some preventive measures, to cover up your plants from the rain. The Soil Moisture Meter works on the same principle as that of any other ordinary moisture meters.
