Tools and Hardware Reviews of Neiko Professional Digital Laser Photo Non-Contact Tachometer - Accurate to 99,999 RPM Measurement
Customer Review: Excellent device
Summary: 5 Stars
The laser tach works as well as you'd expect, measurement range with the reflective tape is 6 feet or more (not sure where Amazon's 500mm description came from, but it's wrong).
The device sends out a beamed laser spot that gets reflected by the tape or any suitably reflective surface. The sensor in the tach picks up the pulses and performs the measurement, displaying in 0.1 RPM steps for speeds up to 999.9 RPM, and 1.0 RPM steps from 1000 to 99999 RPM.
3 AA batteries for economical use with common rechargeables, after the three supplied batteries eventually get used up. They should last quite a while though, using only 40mA during the measurement. The display only comes on when the buttons are actually depressed, so it uses only the minimum amount of battery power- also means it cam't be used for extended unattended measurement however. It has a min and max RPM function, showing the variations in the speed from the measurement.
If you cut a square off from the two strips of supplied reflective tape and just use some scotch tape to temporarily attach it to the object being measured, you can reuse it over and over-
To measure things like fans, you could simply hold the tape behind the fan, and beam the laser through the rotating fan blades. The fan blades will chop the light signal to provide the measurement. You'll need to simply divide the measurement by the number of fan blades, since it'll read multiple counts per revolution.
Very neat item to have around..
