Reviews Summary

I think it is accurate and did work with both non contact and contact they read within a few rpm of each other


Put a small reflective strip included on the shaft or rotating member point and shine the led light on the shaft and read the rpms


Thanks used it once and the only button that matters pushed inside unit
