Why Moisture Gauges are Important
When you search online for the best moisture gauges and sensors on the internet, you’ll find varying results from soil moisture sensors, to wood moisture sensors and humidity sensors. Let us talk about the different types of moisture gauges and sensors, its uses and benefits. We will learn the best features and product ratings available in the market today.
In measuring soil moisture, moisture sensors and gauges 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. For remote sensing in agriculture and hydrology, the soil moisture affects reflected microwave radiation, and gardeners and farmers use portable instruments for measuring soil moisture. Gypsum blocks and tensiometers measure the soil water potential.
It is important that before using a wood, you should know its moisture content for you to be assured of its stability. The two types of wood moisture meters in the market today 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 need to be in contact with the wood, and it can take readings no matter what the wood size, shape and degree of roughness it possess. You can allow usage of remote probes or nails for pin meters or pin sensors, which can be driven at the center of a thick lumber for core wood moisture readings that cannot be reached by pinless meters.
The important features you need to consider when buying moisture sensors and gauges are the pin length, moisture content range, minimum sample size, displays, and built-in temperature correction and built-in species. The pin length should be 1/4 the size the thickness of the wood or board, and you’ll need a longer pin length for thicker board or wood which applies for even moisture gradient where the surface is drier compared to its core. Moisture sensor displays come in four types such as 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.
