- an instrument for measuring longitudinal stress in wires, structural beams, etc.
- an instrument for measuring the surface tension of a liquid.
- an instrument for measuring the tensile strength of a wire, beam, etc
- a device that measures differences in vapour pressures. It is used to determine transition points by observing changes of vapour pressure with temperature
- an instrument for measuring the surface tension of a liquid, usually consisting of a sensitive balance for measuring the force needed to pull a wire ring from the surface of the liquid
- an instrument for measuring the moisture content of soil
