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. 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. 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 are knowledgeable of 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 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 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.
