RPM Measurement

Testo 476 Hand Held Strobeoscope, Pocket Strobe The Testo 476 Pocket Strobe hand-held stroboscope measures and checks rotation and vibration movements. It facilitates the measurement of very small objects or in hard-to-access places. And all without interrupting the production process. Testo 476 is therefore ideal for measuring rpm and inspecting high-frequency moving parts.

Testo 471 Thread Speed and Length Tachometer 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.

Testo 470 Dual Contact Tachometer 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.

Testo 465 Non Contact Tachometer Using Testo 465, rpm can be easily measured without contact. Simply attach a reflector to the object to be measured and then point the visible, red light beam at the reflector and measure.

Testo 460 Pocket Line Optical rpm Measurement Instrument Testo 460 optically measures rpm, e.g. of ventilators and shafts. The measurement spot is displayed on the measurement object with an LED marking. Max./min. values are displayed directly at the press of a button. The backlit display allows the measurement values to be easily read out, even in unfavourable light conditions. Testo 460 is very handy, small and easy to operate.
