Buying Guide – How to Choose the Best Laser Tachometer
Selecting the right laser tachometer involves considering several factors to ensure it meets your specific measurement needs.
Measurement Range
Ensure the tachometer covers the RPM range you need. Most models handle from 2 to 99999 RPM but check for specific limits like 10 RPM minimum.
Choose a device with a range that matches your typical equipment to avoid under or over measuring.
Accuracy and Resolution
Look for accuracy ratings of plus or minus 0.05 percent or better for professional work. Resolution should be 0.1 RPM for detailed tasks.
Higher accuracy ensures reliable data for critical maintenance and diagnostics.
Display Quality
A large backlit LCD screen is essential for visibility in dim workshops. Check for 5-digit displays to read full numbers clearly.
Good display quality prevents reading errors and speeds up data recording.
Measurement Mode
Decide if you need non-contact laser only or a combination with contact modes. Laser is safer while contact works on surfaces without tape.
Dual mode devices offer flexibility but cost more.
Data Features
Features like max min average and memory storage help track performance trends. Data hold buttons let you record readings after taking them.
Advanced data features are useful for detailed reporting and analysis.
Build Quality
Choose a rugged housing with ergonomic design for comfort during prolonged use. Check for included carrying cases or bags for protection.
Durable construction ensures longevity in busy work environments.
Power Source
Most models use standard batteries like 9V or AAA. Consider battery life and availability when choosing.
Auto shut-off functions help conserve battery life during idle periods.
Accessories Included
Reflective tape is necessary for non-contact laser measurement. Ensure the kit includes enough tape and a user manual.
Comprehensive kits reduce the need for additional purchases.
How to Use and Care for Your Laser Tachometer
To use the laser tachometer attach reflective tape to the rotating part if using non-contact mode. Point the laser at the tape and press the measure button to get an instant reading.
For contact measurement use the provided wheel to press against the surface of the rotating object. The device will calculate the RPM based on the wheel speed.
Keep the lens clean and store the unit in its case to avoid damage. Replace batteries when the low battery indicator appears to maintain accuracy.
Frequently Asked Questions
What is a laser tachometer used for?
A laser tachometer measures the rotational speed of objects like motors fans and engines in revolutions per minute. It is commonly used in automotive HVAC and industrial maintenance to ensure equipment is running at correct speeds.
Do I need reflective tape for measurements?
Yes for non-contact laser measurements you must apply reflective tape to the rotating object. The laser reflects off the tape to detect each rotation. Without it the device cannot track speed accurately.
How far can a laser tachometer measure?
Most consumer models work best at distances from 50mm to 500mm but some professional units reach up to 25 feet. Always check the specific measurement range before purchasing for your needs.
What is the difference between contact and non-contact modes?
Non-contact uses a laser to measure speed from a distance which is safer. Contact requires a wheel to touch the surface and is useful when the laser cannot access the part.
How accurate are laser tachometers?
Quality models offer accuracy within plus or minus 0.05 percent. This level of precision is sufficient for most industrial and automotive applications where reliable data is critical.
Can I use a tachometer on hot surfaces?
Non-contact laser models are safer for hot surfaces since you do not need to touch them. Ensure the device is rated for the environment and keep a safe distance during measurement.
How do I store my tachometer?
Store the unit in its provided carrying case to protect it from dust and impacts. Keep it in a cool dry place and replace the batteries when not used for long periods.
Final Thoughts on Choosing the Best Laser Tachometer
The top picks include the Extech 461920 for overall value the NEIKO 20713A for budget buyers and the Extech RPM33 for premium features.
Prioritize accuracy and measurement range based on your specific needs. Features like data memory and display quality also play key roles in your choice.
Remember to check current prices and availability as they may change. Selecting the right model ensures reliable performance for years.
