Typical applications include
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

FAQs:
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.
What do I get in a set?
The Tachometer is supplied with:
Hard Plastic Carry Case
2 x AA Batteries
0.1m Wheel, 6" Wheel
Measuring Tip
Measuring Funnel
Extension
10 x Reflective Strips
