The professional-grade solution for both contact and non-contact RPM testing. Measure rotational speeds, surface linear speeds, and lengths with ±0.01% accuracy. Built to handle heavy industrial demands, motor testing, and engine maintenance effortlessly.
The ErinFita Laser Tachometer utilizes Class 2 laser sight for safe, distant RPM measurements (50-500mm), while providing physical contact adapters for direct, physical rotational speed diagnostics.
Calculate linear surface speed and distance effortlessly. This multi-functional unit supports RPM, total count (REV), speed in various units (I/M, M/M, Y/M, F/M), and length measurements using the integrated 10cm master wheel.
ErinFita stores up to 10 sets of test data, complete with Max, Min, and Average values. Access your historical data points at any time with dedicated buttons to optimize your motor and engine diagnostics.
"The ErinFita Laser Tachometer provides outstanding accuracy and incredible ease of use. Having both laser non-contact and wheel-based contact adapters in one kit solves multiple diagnostic problems in standard mechanical environments."
– Robert Chen, Senior Mechanical Engineer

Frequently Asked Questions
Phenomenal piece of kit! The laser mode makes checking radiator fan and motor RPM incredibly safe and easy, and the physical adapters are perfect for checking shaft speeds.
The accuracy on this tachometer is spot on. I work in conveyor system maintenance, and the linear speed and length measurement features with the master wheel are invaluable.
The built-in memory makes tracking data so much easier instead of having to write down every single value during high/low/average tests. Well worth the price!
