Buying Guide – How to Choose the Best Laser Tachometer
Choosing the right laser tachometer involves understanding your specific measurement needs and the environments in which you will use it. This guide outlines the key factors to consider.
Measurement Range
Ensure the tachometer covers the RPM range of your equipment. Most professional models measure from 2 or 10 RPM up to 99999 RPM, which suits most industrial and automotive needs.
Select a device with a range that exceeds your maximum expected speeds to avoid overflow errors.
Accuracy and Resolution
Accuracy is typically around ±0.05% for quality models. Higher accuracy is crucial for critical maintenance or compliance testing. Resolution indicates the smallest increment the device can display, often 0.1 RPM.
Prioritize accuracy if your work involves precise calibration or safety checks.
Contact vs Non-Contact
Laser tachometers offer non-contact measurement, which is safer for rotating machinery. Some models also include a contact wheel for measuring surface speed, which is useful for conveyor belts.
Decide if you need dual functionality or if laser-only is sufficient for your tasks.
Measurement Distance
Laser tachometers allow you to measure from a safe distance. Check the maximum distance supported, which ranges from a few inches to several feet depending on the model.
Choose a longer range if you need to test dangerous or hard-to-reach machinery.
Display Quality
A clear, backlit LCD is essential for reading results in dim workshops. Look for larger screens with clear digits to reduce eye strain during prolonged use.
Backlight functionality ensures visibility in low-light garage or industrial settings.
Data Memory
Advanced models offer memory to store Min, Max, and Last values. This feature helps track performance over time without manual note-taking, which is useful for diagnostics.
If you need to analyze trends, prioritize a unit with data storage capabilities.
Build Quality and Durability
Industrial tools should have rugged housings like double-molded plastic to withstand drops and dust. Lightweight designs improve portability for technicians on the move.
Consider the build material based on your working environment, such as rough industrial sites.
Power Source
Most tachometers use standard batteries like 9V or AAA. Some include auto shut-off to preserve battery life during inactivity.
Check the battery type and whether the device includes batteries in the package.
How to Use and Care for Your Laser Tachometer
To use a laser tachometer, attach a small piece of reflective tape to the rotating part of the object you are measuring. Ensure the surface is clean and the tape is flat to avoid inaccurate readings.
Hold the device steady and aim the laser at the tape mark from the recommended distance. Press the measurement button and wait for the reading to stabilize on the display screen.
After use, clean the lens with a soft cloth and store the device in a protective case. Replace batteries when the low battery indicator appears to prevent data loss during critical measurements.
Frequently Asked Questions
Do laser tachometers work on all surfaces?
Laser tachometers require a reflective surface to function correctly. Most objects lack enough reflectivity, so you must apply the included reflective tape to the target area for accurate measurements.
How safe are laser tachometers?
Most handheld laser tachometers use Class 2 lasers which are safe for casual viewing. However, you should avoid staring directly into the beam or pointing it at the eyes or others.
What is the minimum distance to measure?
Minimum distance varies by model but is often between 2 inches and 50mm. Check the user manual for your specific unit to ensure you are within the correct operational range.
Can I use this on moving vehicles?
Yes, but the tachometer must remain steady. It measures rotational speed, not linear vehicle speed. Use it on wheels or shafts where you need to verify rotation rates during testing.
What happens if I miss the target?
If the laser does not hit the reflective mark, the device will display zero or erratic values. Reposition the device until it locks onto the target for a stable reading.
How do I calibrate the tachometer?
Most modern laser tachometers do not require user calibration. Models like the Monarch PLT200 come with NIST-traceable certificates to ensure accuracy out of the box.
