In surface science, a tensiometer is a measuring instrument used to measure the surface tension (γ) of liquids or surfaces. Tensiometers are used in research and development laboratories to determine the surface tension of liquids like coatings , lacquers or adhesives .
Tensiometer may refer to one of a number of devices. The two most common are: Tensiometer (surface tension) an instrument used to measure the surface tension of liquids;
A tensiometer in soil science is a measuring instrument used to determine the matric water potential (soil moisture tension) in the vadose zone. This device typically consists of a glass or plastic tube with a porous ceramic cup and is filled with water .
A classical torsion wire-based du Noüy ring tensiometer. The arrow on the left points to the ring itself. The most common correction factors include Zuidema–Waters correction factors (for liquids with low interfacial tension), Huh–Mason correction factors (which cover a wider range than Zuidema–Waters), and Harkins–Jordan correction factors (more precise than Huh–Mason, while still ...
Bubble pressure tensiometer produces gas bubbles (ex. air) at constant rate and blows them through a capillary which is submerged in the sample liquid and its radius is already known. The pressure ( P ) inside of the gas bubble continues to increase and the maximum value is obtained when the bubble has the completely hemispherical shape whose ...
The plate is cleaned thoroughly and attached to a balance with a thin metal wire. The force on the plate due to wetting is measured using a tensiometer or microbalance and used to calculate the surface tension using the Wilhelmy equation: = ()
In surface science, an instrument called a contact angle goniometer or tensiometer measures the static contact angle, advancing and receding contact angles, and sometimes surface tension. The first contact angle goniometer was designed by William Zisman of the United States Naval Research Laboratory in Washington, D.C. and manufactured by ramé ...
A tension meter is a device used to measure tension in wires, cables, textiles, Mechanical belts and more. Meters commonly use a 3 roller system where the material travels through the rollers causing deflection in the center roller that is connected to an analog indicator or load cell on digital models.
