RS PRO Tachometer Best Accuracy ±0.05 % - Non Contact LCD

Introducing the RS PRO RS AT-6 Tachometer, a professional and high-quality laser tachometer (digital rotary measuring instrument) designed with the latest measuring technologies in mind. Built with a durable and robust housing, this tachometer allows for fast and accurate non-contact optical measurements of RPM and surface speed. The ergonomically designed body makes it a comfortable device to use at any location and the backlit LCD screen makes it easy to read measurements, even in low light conditions. This RS PRO laser light tachometer is a must-have device for any user working in close distance to high-risk machines or where the access is restricted.

A tachometer or revolution counter is a tool that is used to measure the rotation speed of an object. These devices often measure in RPM (Revolutions Per Minute) units, which measures the frequency of the rotation and would be most familiar alongside a speedometer in a car. This tool is important in the implementation and day to day operations and maintenance of machinery and systems and it is also beneficial for use in research and development laboratories. Tachometers are typically used for measuring:

• The speed of rotating equipment such as engines, turbines, fans, wheel, shafts, rollers


• Travelling speed of belts and conveyors


• Length of long products such as wire, fibre, steel, wood, etc.


• The speed of travel and length of sheet products such a films and foils

Yes, the tachometer is supplied with a 9V battery

The tachometer's optical sensor uses a beam of laser light to measure the speed of rotation of the wheel or shaft by using reflective tape or mark as a control target. It measures differences in frequency of the reflected light.

Yes, the unit can be calibrated to RSCAL or ISOCAL standards
