Laser has added new portable tachometer to its tool range. The new tool, part number 6610, is used for non-contact measurement of rotational speeds. Uses include maintenance and adjustment of various machines, conveyor belts, motors and belt drives. It uses photoelectric, anti-jamming and junction laser technology to provide non-contact measurements over a wide range from 2.5 – 99,999 RPM and with great accuracy (± 0.05% + 1 digit).

A reflective mark is placed on the object to be measured with white reflective tape and this is used as a target for the instrument's integral laser light beam. The detecting distance is 50-500mm, and the sample time is just .8 sec, so that the RPM is displayed on the large and clear LCD display almost instantly.

The digital tachometer has a memory function (minimum, maximum and last values) and 96 sets of continuous data can be saved. It includes a low battery indicator, and three AA batteries are included. The tool which is now available from Laser stockists, is CE certificated and ROHS compliant.
