  2. 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 ...

    en.wikipedia.org/wiki/Tensiometer_(soil_science)

    Electronic tensiometer probe: (1) porous cup; (2) water-filled tube; (3) sensor-head; (4) pressure sensor A tensiometer in soil science is a measuring instrument used to determine the matric water potential ( Ψ m {\displaystyle \Psi _{m}} ) ( soil moisture tension) in the vadose zone .

  4. Moisture meter - Wikipedia

    en.wikipedia.org/wiki/Moisture_meter

    Measuring water leakage in exterior wall with Trotec T660 Moisture Measuring Device, using dielectric measurement method (indicative). Moisture meters are measuring instruments used to measure the percentage of water in a given substance, as physical properties are strongly affected by moisture content and high moisture content for a period of time may progressively degrade a material.

    Hemispherical electron energy analyzer. A hemispherical electron energy analyzer or hemispherical deflection analyzer is a type of electron energy spectrometer generally used for applications where high energy resolution is needed—different varieties of electron spectroscopy such as angle-resolved photoemission spectroscopy (ARPES), X-ray photoelectron spectroscopy (XPS) and Auger electron ...

  8. Soil test - Wikipedia

    en.wikipedia.org/wiki/Soil_test

    A soil test is a laboratory or in-situ analysis to determine the chemical, physical or biological characteristics of a soil. Possibly the most widely conducted soil tests are those performed to estimate the plant-available concentrations of nutrients in order to provide fertilizer recommendations in agriculture.

  9. Cone penetration test - Wikipedia

    en.wikipedia.org/wiki/Cone_penetration_test

    A friction sleeve was added to quantify this component of the friction and aid in determining soil cohesive strength in the 1960s. [1] Electronic measurements began in 1948 and improved further in the early 1970s. [2] Most modern electronic CPT cones now also employ a pressure transducer with a filter to gather pore water pressure data. The ...
