Tachometers & RPM Meters
About Tachometers & RPM Meters
Available in both contact and non-contact forms, tachometers measure the overall RPM (revolutions per minute) of machinery to ensure correct installation and use.
Non-contact tachometers work by using reflective materials that the tester can read as it revolves. By determining the amount of times that the system revolves, the tachometer can gain a reading of overall RPM and displays this as a value on the built-in screen. Direct contact tachometers are best for more accurate measurements, but require more careful setup.
