Tachometers provide fast and accurate RPM measurements for motors, shafts and rotating machinery. Choose from contact and non-contact instruments for maintenance, diagnostics and rotational speed testing across mechanical and industrial applications.
Tachometers
About This Category
Measuring rotational speed is an important part of inspecting, maintaining and troubleshooting motors and other rotating equipment. Tachometers provide RPM readings that allow technicians to check operating speeds, compare equipment performance and identify unexpected changes in machinery behaviour.
Different measurement methods are available depending on the equipment and whether physical access to the rotating component is practical. Non-contact tachometers typically use an optical or laser-based measurement method to determine rotational speed without touching the moving component. This makes them particularly useful when measuring motors, fans, pulleys, shafts and other equipment where direct contact would be difficult or undesirable.
Contact tachometers take measurements through physical contact with the rotating component and can be useful where direct mechanical measurement is preferred. Some instruments combine contact and non-contact measurement in a single device, giving maintenance technicians greater flexibility when working with different types of machinery.
When selecting a tachometer, consider the expected RPM range, accuracy, measurement distance and whether contact measurement is required. Functions such as MIN/MAX recording, data hold and memory can also make it easier to capture and compare readings during machinery inspection and maintenance.
Rotational speed is often assessed alongside other electrical and mechanical parameters when troubleshooting motors and industrial equipment. For related diagnostic instruments, browse our electrical testers, or view the complete environmental testers range.
