I was a little worried that it may not work based on reviews. The 5-digit LCD makes reading measurements simple and easy. It works on quartz crystal and has automatic range selection one-chip LSI circuit. To take a measurement, apply the reflective marks provided to the surface being measured, then aim the laser, push the side button and the RPM reading is immediately displayed. It can work from a distance of 3.5 feet and can store the last, maximum, and minimum value in its memory. The package comes with a case, reflective tape, and a manual. It has a range of 2.5 – 99,999 RPM and a sampling time of one second. The unit works by sending a laser beam on the rotating surface. This non-contact laser tachometer comes with LCD. No white light tachometer that I’ve used could do that.” – Amazon’s Customer Review.Īvailable here. If measuring a black object, you can draw a thick line with a silver sharpie marker and not even bother with the tape. I have used this tachometer in bright environments without any problems. While you still need to use a reflective tape to allow for the reflection pickup, the laser is so much brighter than white light tachometers. The main benefit of this tachometer is the laser output. “This tachometer is very easy to use and has a great measuring range. This device can also count the moving objects passing through the instrument’s field of view. The package comes with a reflective tape, carrying case and battery. It has a battery indicator and can automatically shut off when not in use. The built-in internal memory recalls minimum and maximum values stored previously. You can easily calculate the RPM of a rotating object without contact. This small photo tachometer is non-contact, and the built-in laser identifies target area.
