The Best 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 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 crucial that these proxy should be well calibrated with soil moisture, 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 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. 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.

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. 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. 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.
