Tachometers

Tachometers help maintenance, inspection, and production teams measure the speed of rotating equipment and moving surfaces. This category includes contact, photo, laser, and stroboscopic instruments for checking RPM, observing operating components, measuring surface speed, counting revolutions or moving objects, and supporting troubleshooting on equipment such as motors, fans, pumps, conveyors, turbines, compressors, and blowers.

Helpful Buying Guide

Choose a Tachometer for the Measurement Task

Start with how the measurement will be taken: without touching a rotating target, through direct contact, or by viewing apparent frozen motion during operation. Then compare the readings, ranges, accessories, display features, and memory functions that fit the equipment checks your team performs.

Use Cases

Check speed, count motion, or inspect rotation

Use tachometers to check rotating-object RPM, track revolutions, measure moving-surface speed, or count moving objects. Stroboscopic models help users observe rotating components while equipment is operating.

How to Choose

Match the measurement method to access

Choose a non-contact photo or laser model when direct access is less practical. Select a contact-capable model for direct RPM or surface-speed readings, and consider a dual-mode instrument when both approaches are needed.

Applications

Support maintenance and production checks

Representative uses include evaluating gears, fans, pumps, motors, conveyors, turbines, compressors, blowers, and other rotating or moving equipment.

Additional Information

Compare display, memory, and included accessories

Depending on the model, available features include backlit or rotatable displays, stored minimum, maximum, average, or last readings, reflective tape, contact adapters, wheel adapters, cone tips, and carrying cases.

Measurement Methods

Contact, non-contact, and stroboscopic options

Non-contact photo and laser tachometers measure rotating-object speed without touching the target. Contact models take direct readings and can support surface-speed checks. Combination instruments provide both methods in one tool, while digital stroboscopes use freeze-motion viewing to examine rotating components.

  • Non-contact options are available for RPM checks from up to 12 inches or up to 1.6 ft away, depending on the model.
  • Contact models can measure RPM and, on applicable models, linear surface speed in ft/min or m/min.
  • Stroboscopes support non-contact observation of moving equipment from 100 to 10,000 FPM/RPM.
Readings and Range

Select the measurements your work requires

RPM capability varies by instrument and measurement mode. Some models add revolution counting, moving-object counting, surface-speed measurement, or length measurement for broader maintenance and production tasks.

  • A mini laser photo model supports 2 to 99,999 RPM and counts up to 99,999 revolutions.
  • One combination model measures contact RPM from 5 to 99,999 RPM and photo RPM from 0.5 to 20,000 RPM.
  • Surface-speed-capable models use contact adapters to measure moving surfaces.
Practical Features

Consider visibility and recordkeeping needs

For work in changing positions or lower-light areas, compare display style and illumination. Memory functions can also help teams compare recent readings during equipment checks.

  • Available displays include 5-digit LCD, backlit LCD, and rotatable backlit display options.
  • Memory functions may recall minimum, maximum, average, last, or recent readings.
  • Included accessories vary and can include reflective tape, batteries, cone tips, funnel and wheel adapters, contact adapters, and protective storage.
FAQ

Common questions before buying

What is the difference between a contact and non-contact tachometer?

A contact tachometer measures through direct contact, while a photo or laser tachometer measures RPM without touching the target.

Can a tachometer measure surface speed?

Select contact and combination models support surface-speed readings in ft/min or m/min when used with applicable contact adapters.

What does a stroboscope do?

A digital stroboscope makes rotating parts appear stationary so users can observe and analyze moving equipment during operation.

Do tachometers store readings?

Some models provide memory for last, minimum, maximum, average, or recent readings.
