Handheld tachometer

The compact RheinTech Rotaro Digital handheld tachometer has two measuring methods: the optical and therefore non-contact method measures up to 99,999 rpm and the mechanical method, using an adapter and various probes to measure up to 19,999 rpm.

The non-contact method uses a precise beam of light together with a piece of reflective tape affixed to the rotating element to accurately measure its rotational speed. The result appears immediately on the 5-digit LCD. The distance between the tachometer and the test object can be up to 600 mm. The mechanical method permits the user to connect an adapter that accepts a variety of contact probes, as well as a surface speed wheel, for precise measurement of contact rpm or surface speed and length.

The easy-to-read LCD provides a wealth of information including the measured value, selected engineering units, as well an indication of the selected measuring mode - contact or non-contact.
