Is Thermal Camera A Good Measurement For Wetness
Looking to add a moisture meter to your tool pocketbook? Here's what you demand to know to notice the right tool for you.
Wet meters come in two varieties: pin and pinless. A pivot moisture meter can provide quantifiable results but needs to pierce the surface to have measurements; a pinless moisture meter is faster and not-destructive, but just provides a relative reading.
Pin Wet Meters
Pin moisture measurement requires the physical insertion of the two pin probes into the wall (or material in question). So an electrical electric current is run between the two probes, and the material's wet content is determined by measuring the resistance the current encounters. Water, with its dissolved salts and impurities, conducts electricity while building materials such every bit forest practice not, meaning dry walls and floors offer more resistance. The wetter the material, the more conductive it is.
Because pin meters are sensitive to temperature and the blazon of material being measured, a good meter should come up with options to compensate for the temperature and material encountered. The FLIR MR55, for instance, comes with a congenital-in library of 11 different fabric groups and automatically compensates for ambient temperature.
The takeaway: pivot moisture meters provide you with a quantifiable measurement of the pct of moisture in a material, just require some damage to the material being measured.

Pinless Moisture Meters
The reward of pinless moisture meters is they won't impairment your walls—but there's a catch. A pinless meter is a "relative" or unitless measurement device. Unlike a pin moisture meter that measures resistance, the pinless meter measures an electric property of the material called relative permittivity.
To fully understand this measurement, information technology needs to be compared to a known dry sample of the same material. The best way to use a pinless meter is to make a measurement of a material of a known dryness, and so make a measurement of an particular of the same material, thickness, and construction.
Whatever ascension in reading indicates moisture, or the presence of some other conductor or high permittivity textile (a metal stud behind the wall, for instance, would produce loftier readings). Because of this, taking multiple measurements over the suspected area is highly recommended.
Pinless moisture meters may have a flat sensor that needs to be placed flush against the surface of the fabric, or may have a ball probe like the FLIR MR59 that allows you to easily measure out into corners and effectually baseboards.
If you think you lot need both a pin and pinless wet meter for your work, so the FLIR MR60 provides both an integrated pinless sensor and an external pin probe.
Infrared Guided Measurement
Some other feature you may want to consider on a moisture meter is thermal imaging. FLIR meters equipped with Infrared Guided Measurement (IGM) apply thermal imaging to aid quickly locate potential wet issues. Instead of hunting around for hidden leaks or signs of moisture, you can scan large areas to visually target the problem and and then either verify information technology using the congenital-in pinless meter or an accessory pin probe. Larn more than most detecting moisture issues using thermal imaging:
Moisture meters with IGM include the FLIR MR277, the MR176, and the MR160.
