Rotaro Tw Digital Handheld Tachometer

The Rotaro Tw digital hand-tachometer is a device for measuring rotational speed and velocity, as well as length. The compact device has two measuring methods. One is optical, and therefore non-contacting; the other is mechanical using an adapter and various probes. With the optical method, it focuses a beam of light at a thin sticker attached to the object, which reflects it at the speed of rotation. The result appears immediately on the 5-digit LCD. The distance between the Rotaro Tw digital hand tachometer and the test object can be up to 600 mm. The Rotaro Tw comes with a special adapter to enable the measurement in connection with welding wire and is the perfect fit for typical applications such as calibration, service and maintenance work within the welding and wire industry.
