How to Find Moisture Gauges and Sensors
If you search on moisture sensor and gauges online, there are varying results from soil moisture sensors, to wood moisture sensors and humidity sensors. In this article, we will talk about the different types of moisture gauges and sensors, its uses and benefits. We will learn about the best features and product ratings and reviews available in the market today.
When it comes to measuring the soil moisture, soil moisture gauges and sensors measure the soil’s volumetric water content by indirectly using other properties of soil like dielectric constant, electrical resistance, or neutrons interaction which are considered proxy for the soil’s moisture content. It is important to have a property and soil moisture calibration and this depends on the soil type, electric conductivity or temperature. Gardeners and farmers use portable instruments for measuring soil moisture content, and for remote sensing in agriculture and hydrology, the soil moisture affects reflected microwave radiation. Soil water potential can be measured using sensors such as tensiometers and gypsum blocks.
In order for you to know whether a wood is stable to use or not, it is important that you know its moisture content. The two kinds of wood moisture meters are pin and pinless moisture meters, wherein both types measure the effect of moisture on an electromagnetic field (pinless) or an electromagnetic current (pin). Pinless meters are portable that it can be taken into the lumberyard for testing the wood before buying it, and it can scan an entire board without putting holes on it. Pin meters take readings no matter what the wood size, shape and degree of roughness it has, requiring two pins making in contact with the wood. Pin meters allow usage of remote probes or nails that can be driven at the center of a thick lumber for core wood moisture readings that cannot be reached by pinless meters.
Before buying your own moisture meter or moisture sensor, you need to take into consideration the pin length, moisture content range, minimum sample size, displays, and built in temperature correction and built-in species. The rule of the thumb is you need a longer pin length for thicker board or wood which is 1/4 of its thickness, and this applies for even moisture gradient where the surface is drier compared to its core. The four types of moisture sensor displays are analog, LED, digital LCD, and digital LED.
It is important to purchase only from reputable and trusted dealers for the best moisture meter or moisture sensors for whatever need you have.
