2. Moisture meter - Wikipedia

   en.wikipedia.org/wiki/Moisture_meter

   The second type of moisture meter relies on the dielectric properties of wood. The meter incorporates two pads which serve as rubber electrodes that transmit and receive a signal when pressed into the wood substrate. The pad type moisture meter is non-invasive in nature and requires only surface contact with the wood to obtain a reading.

3. Concrete moisture meter - Wikipedia

   en.wikipedia.org/wiki/Concrete_moisture_meter

   A concrete moisture meter is a type of moisture meter used by installers of flooring to measure the moisture levels of concrete. These meters have been used for decades to measure the moisture content in different materials and substances. Concrete meters have evolved from the successful wood moisture meter as flooring contractors tried to use ...

4. Soil moisture sensor - Wikipedia

   en.wikipedia.org/wiki/Soil_moisture_sensor

   A simple soil moisture sensor for gardeners. Soil moisture sensors measure the volumetric water content in soil. [1] Since the direct gravimetric measurement of free soil moisture requires removing, drying, and weighing of a sample, soil moisture sensors measure the volumetric water content indirectly by using some other property of the soil, such as electrical resistance, dielectric constant ...

5. TDR moisture sensor - Wikipedia

   en.wikipedia.org/wiki/TDR_moisture_sensor

   A TDR waveguide with exposed wires. In the waveform analysis a sensor (usually a probe) is placed in the material to be tested. The sensor contains a waveguide consisting of two, three, or more parallel wires which is connected via a coaxial cable to a voltage pulse generator which sends precisely defined voltage pulses into the sensor.

6. Moisture analysis - Wikipedia

   en.wikipedia.org/wiki/Moisture_analysis

   Moisture analysis covers a variety of methods for measuring the moisture content in solids, liquids, or gases. For example, moisture (usually measured as a percentage) is a common specification in commercial food production. [1] There are many applications where trace moisture measurements are necessary for manufacturing and process quality ...

7. Neutron moisture gauge - Wikipedia

   en.wikipedia.org/wiki/Neutron_moisture_gauge

   A neutron moisture meter is a moisture meter utilizing neutron scattering.The meters are most frequently used to measure the water content in soil or rock. The technique is non-destructive, and is sensitive to moisture in the bulk of the target material, not just at the surface.
