This professional tachometer (digital rotary measuring instrument) from RS PRO offers the latest technologies in a robust and durable housing and allows for fast and accurate measurements of rotational and linear speeds. It can be used as both an optical tachometer to measure rotations and also a contact tachometer reader to measure rotational speed, RPM, linear speed and distance. The ergonomically designed body makes it a comfortable device to use at any location.

• Measures max., min., and average values in both metric and imperial units
• Clear and easy to read LCD display with a memory function
• Supplied with a selection of accessories
• Calibration Certificate (supplied with a calibrated versions only)
• 3 Years warranty

This tool is just as important in the implementation and day to day operations of machinery and systems as it is for maintenance and would also benefit research and development laboratories. Tachometers are typically used for measuring e.g:

• The speed of rotating equipment such as motors, 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 as a complete, ready to use set with battery, case and all required accessories. The battery is non-rechargeable and has to be replaced if necessary.

How does an optical sensor work?

The tachometer's optical sensor uses a beam of led light to measure the speed of rotation of the wheel or shaft. It measures differences in frequency of the reflected light.

How does contact tachometer work?

The contact tachometer's integral spinning wheel sensor has to be placed directly on the rotating shaft or disc then tachometer measures pulses and converts them into RPM, linear speed or distance units.
