The Best Moisture Gauges and Sensors

When you search for 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 about the best features and product ratings and reviews available 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. 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. Water potential can also be measured by soil water potential sensors and it includes 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 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). A pinless meter can scan an entire board without having holes on it, and it is portable that it can be taken into the lumberyard for testing the wood before buying it. Pin meters can read moisture content no matter what the wood size, shape and degree of roughness it possess, 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 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. In choosing the pin length, the rule of the thumb is you need a longer pin length for thicker board or wood which is 1/4 of its thickness, 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.

It is important to purchase only from reputable and trusted dealers for the best moisture meter or moisture sensors for whatever need you have.
