Buying Guide – How to Choose the Best Laser Tachometer
Selecting the right tachometer depends on your specific needs for range accuracy and features.
Measurement Range
Ensure the tachometer covers the RPM range you need. Most models support 0 to 99999 RPM but some may have lower minimums like 2.5 RPM.
Check that the device meets your max and minimum speed requirements before buying.
Accuracy Level
Look for accuracy within 0.05 percent for professional use. This precision helps in critical maintenance tasks.
Higher accuracy ensures reliable data for safety and quality checks.
Display Quality
A backlit LCD is essential for use in dark garages or workshops. Larger displays make reading numbers easier.
Choose a clear display to avoid errors during quick inspections.
Contact vs Non Contact
Non contact laser tachometers are safer for spinning parts. Contact models are useful for linear speed measurements.
Decide if you need both modes or just one for your work.
Memory Features
Devices that store max min and average values help track trends. This saves time on manual recording.
Look for memory functions if you need to analyze data over time.
Portability
Lightweight and compact designs are easier to carry in a toolbox. Consider weight and size for field use.
Choose a model that fits comfortably in your hand for long periods.
Battery Life
Auto shut off and low battery indicators extend usage. Standard 9V or AAA batteries are common.
Check battery type and power features for convenience.
Certifications
For regulated industries, NIST traceable calibration is key. CE marks ensure safety compliance.
Verify certifications if you need to meet quality standards.
How to Use and Care for Your Laser Tachometer
Apply reflective tape to the rotating part for accurate laser targeting. Ensure the surface is clean and visible.
Aim the laser at the target from the recommended distance. Press the measurement button and wait for the reading.
Clean the lens regularly and store in a case to protect optics. Replace batteries when the low indicator appears.
