Buying Guide – How to Choose the Best Laser Tachometer
Choosing the right laser tachometer requires understanding your specific measurement needs and environment.
Measurement Accuracy
Accuracy is critical for ensuring your machinery runs at optimal speeds. Look for devices that offer at least +/- 0.05 percent precision to avoid costly errors in performance testing.
Prioritize models with high accuracy ratings if you work in regulated environments where exact data matters.
Range and Resolution
The RPM range should cover the speeds of the equipment you typically test. Most models go up to 99,999 RPM but check the minimum threshold to ensure slow motors can be measured.
Resolution determines how precise the display is. A resolution of 0.1 RPM allows you to detect very small changes in speed.
Contact vs Non-Contact
Non-contact laser measurement is safer for high speed or hazardous machinery. Contact modes are useful when you need to measure linear speed or when reflective tape cannot be applied.
Consider a dual-mode unit if you work on a variety of equipment that requires both types of measurement.
Display Readability
A clear display is essential for reading values quickly on busy job sites. Look for backlit screens if you often work in dimly lit areas like engine bays or basements.
Larger screens with high contrast digits reduce eye strain during extended use.
Data Storage Features
Some tachometers store min max and average values automatically. This is useful for analyzing trends over time without manually recording numbers.
If you need to compile reports for clients check that the device supports memory retention or data export.
Durability and Build
Worksite tools face drops and dust regularly. Rugged housing with rubberized grips ensures the device can survive daily wear and tear.
Look for models that come with protective cases to extend the lifespan of the optics.
Power Source
Most units run on standard batteries like 9V or AAA. Check how long the device lasts on a single charge to avoid interruptions during critical tasks.
Auto shut-off features help preserve battery life when the tool is left idle.
Calibration Requirements
For professional use NIST traceable calibration is often required for compliance. Ensure the device comes with a certificate if you work in regulated industries.
Even for DIY use factory calibration ensures consistent accuracy out of the box.
How to Use and Care for Your Laser Tachometer
To begin using your laser tachometer turn it on and select the appropriate mode for your task. Attach a piece of reflective tape to the rotating surface if using non-contact mode.
Aim the laser at the reflective tape from a safe distance and press the measurement button. Keep the device steady until the display shows a stable reading.
Clean the lens regularly with a soft cloth to maintain accuracy. Store the device in its case to protect it from dust and physical damage.
Frequently Asked Questions
Do I need reflective tape for all measurements?
Reflective tape is essential for non-contact measurements on dark or shiny surfaces. Some models can read natural reflective marks but using the included tape ensures the best results.
Can a laser tachometer measure electric motors?
Yes laser tachometers are ideal for measuring electric motor speeds safely. Just ensure you place the reflective tape on the shaft or a visible rotating part.
How far can I measure with a laser tachometer?
Most models work within 2 to 10 feet but premium units can reach up to 25 feet. Check the specific specs for your model to know its maximum range.
What is the difference between contact and non-contact tachometers?
Non-contact models use a laser to measure speed from a distance. Contact models use a physical wheel to touch the rotating surface which is useful for linear speed measurements.
Why does my reading fluctuate?
Fluctuations can happen due to inconsistent lighting or improper tape placement. Ensure the tape is flat and clean and hold the device steady during measurement.
How do I change the batteries?
Most units have a removable battery cover on the back. Use a small screwdriver if needed and insert fresh batteries paying attention to polarity.
Final Thoughts on Choosing the Best Laser Tachometer
The Extech RPM33 offers the best overall versatility with its dual mode capabilities and data tracking. For those on a budget the NEIKO 20713A provides reliable performance at an affordable price point.
Consider your specific needs regarding accuracy and safety distance when making a final decision. Professional environments should lean towards models with calibration certificates for compliance.
