Rotational speed monitor
TESTO
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.
* Easy one-hand operation
* Measurement of rpm, speeds and lengths
* "Low Batt" warning
* Robust design with SoftCase (protective case)
* Storage of mean/max./min. values, last reading
* Measurement distance up to 600 mm (optical measurement)
