How to Find Moisture Gauges and Sensors

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. This article will increase your awareness and understanding on the different types of moisture gauges and sensors, its uses and benefits. We will learn the best qualities of the best moisture sensors and gauges offered in the market today.

For soil moisture gauges and sensors, it primarily 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.

It is important that before using a wood, you should know its moisture content for you to be assured of its stability. 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). The benefits of having a pinless meter is it scans an entire wood board without putting holes on it, and this can be taken into the lumberyard for testing the wood before buying 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. For thick lumber or woods, pin meters or pin moisture sensors 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.

Before purchasing a moisture sensor, meter or gauge, it is important to consider the important features such as 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. The four types of moisture sensor displays are analog, LED, digital LCD, and digital LED.

Be well-informed, you can read product ratings and reviews where you can buy the best moisture sensor and gauges in the market today, only from the most trusted and reliable dealers and manufacturers.
