Place of Origin: Hong Kong


This is a digital, battery-powered portable optical tachometer operates up to 500mm from a reflective target using a laser light source. It allows safe, direct line-of-sight viewing of both the rotating target and the display at the same time and gives RPM reading exactly with no guessing or errors. It provides fast and accurate RPM and surface speed measurements and combines both contact and non-contact models for use in all applications. Gives 3 measurement options in one meter, photo or laser measurement, contact measurement and surface speed measurement:

Photo/laser measurement: It measures the rotational speed using a visible red light beam from a powerful LED. Just attach a reflective sticker to the rotating part and point the beam on the mark from a safe distance.

Contact measurement: It comes with contact tips that can be used to touch the rotating axle. This is great when a reflcetive tape can not be attached, e.g. due to grease or water.

Surface speed measurement: With the precision wheel you can measure the surface speed in m/min. This is great for all kinds of belts. Conversion table to ft/min, inch/min included!
