Testo 470, the ideal combination of optical and mechanical rpm measurement. An optical measurement becomes a mechanical measurement by simply attaching an adapter for probe tip or surface speed disc. 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.
Features:
Easy one-hand operation
Measurement of rpm, speeds and lengths
"Low Batt" warning
Robust design with Soft Case (protective case)
Storage of mean/max./min. values, last reading
Measurement distance up to 600 mm (optical measurement)
