One tachometer, multiple measurements: The testo 470 tachometer carries out rpm measurements on motors, shafts, fans, etc., but that’s not all. With this handy instrument, you can also determine speeds and lengths (e.g., of conveyor belts and rotors). 

Comes complete with a calibration Certificate Traceable to National Standards when purchased new.

Product Description

Do you need to measure the rpm of rotating objects or record the length and speed of conveyor belts and rotors? The testo 470 tachometer is a compact tool that makes it possible to carry out these measurements.

Multiple functions in one tachometer

The rpm measuring instrument testo 470 can be operated with one hand, offers an optimum combination of optical and mechanical rpm measurement.  By simply attaching an adapter for a probe tip or a speed disc, the optical measurement becomes a mechanical one.  This allows speeds and lengths to be measured additionally.  For optical, simply attach a reflective marker to the measurement object, point the visible measurement spot at the reflective tape marker and measure.  The testo 470 stores mean, min, max values. 

In the case of optical rpm measurement, you can use the testo 470 tachometer to record how fast a rotating object rotates. Thus, for example, you can check whether motors, shafts and fans are functioning correctly in order to spot any impending defects due to overload at an early stage.

For rpm measurement, simply stick a reflective marker on the measurement object and aim the visible red beam at the reflective marker. The measurement can then start (at a distance of up to 600 mm between tachometer and measurement object). The tachometer is easy to operate using one hand.

However, the testo 470 tachometer not only provides the functions of an optical tachometer, it also functions as a mechanical tachometer: Attach the adapter for the probe tip and measure the rpm mechanically. Attach the wheel to also measure speeds and lengths of rotors/conveyor belts.

You get the testo 470 tachometer in a transport case with practical accessories (reflective markers, soft case, etc.).
