Measurement of the speeds and lengths of threads.

With the Testo 471, the lengths and speeds of threads, wires or (glass) fibres can be measured. The plug-in thread measurement adapter has a very lightly running, specially coated measuring wheel and a deflection pulley, in order to be able to measure with as little tension as possible. Optical measurement with reflective tape and mechanical measurement with a surface speed disc or measurement tip are also possible.
