Pocket-sized RPM Meter from Testo

Tachometers, also called RPM meters, are designed to measures the rotational speed of the shaft or disc while the machines are in motion. This hand-held model provides its users with a comfort level to carry it to the desired location. These devices use a light source of a spinning wheel to make measurements. They help monitor any machine or turbine health. In specific applications, traffic speed, volume or flow, angular momentum can also be estimated with these measuring instruments. 

Common Applications of RPM Meter

The typical applications of the Tachometer or the RPM meter are:

  • For measuring rotational speed
  • To calculate the flow of the liquid with the help of an attached wheel
  • Used in the medical sector to measure blood flow
  • To display the rate of engine crankshaft rotation

This crucial instrument conducts essential functions like monitoring motor speed, counting, process control and many others in areas wherever applicable.
