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. 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 crucial that these proxy should be well calibrated with soil moisture, and this depends on the soil type, electric conductivity or temperature. For measuring soil moisture, gardeners and farmers use portable instruments, 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. In measuring the moisture content of the wood, there are two types of sensors or meters available in the market today which are the 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. 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 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. There are four types of displays which are analog, digital LCD, digital LED and 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.
