RS PRO RS AT-6 Non-Contact Tachometer

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.

Features and Benefits:

  • This RS PRO non-contact tachometer has been designed with a durable and robust housing for use in challenging environments while offering an intuitive and easy to use interface for optimum ease of use

  • The handheld device offers a wide measuring range and high resolution for accurate and reliable results

  • A non-invasive way of measuring RPM and surface speed, especially in areas where it may be dangerous or difficult for the user to reach

  • The tachometer has a clear and easy to read backlit LCD display, allowing it to be used in environments with low lighting or where visibility may be poor

  • Built-in memory allows the maximum, minimum and last value read to be stored

  • The tachometer unit is powered by a 9V battery (included) or a 6V exterior DC mains power supply

  • Supplied with a 9V battery and convenient carry case for easy storage and device protection when not in use


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

Is this tachometer supplied with a battery?

Yes, the tachometer is supplied with a 9V battery

How does an optical sensor work?

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.

Can this unit be calibrated?

Yes, the unit can be calibrated to RSCAL or ISOCAL standards and can be found here:
