Auxanometer
An auxanometer (Gr. auxain, "to grow" + metron, "measure") is an apparatus for measuring increase or rate of growth in plants.[1]
In case of an arc-auxanometer (see picture), there is a wire fixed with the plant apex on one end and a dead-weight on the other. It passes over a pulley which has a pointer attached to it. When the plant's height increases, the pulley rotates and the pointer moves on a circular scale to directly give the magnitude of growth.[2]
Sensitive auxanometers allow measurement of growth as small as a micrometer,[3] which allows measurement of growth in response to short-term changes in atmospheric composition.[4] Auxanometers are used in the laboratory,[4] the field,[5] and the classroom.[6]
