The Fluke 931 tachometer is a handheld tachometer, which integrates the contact and non-contact speed measurement functions and can accurately measure the revolutions per minute (RPM) or surface speed and distance. Fluke 930 is equivalent to a Fluke 931 with minimum configuration. With only the non-contact measuring function provided, it's more affordable and offers consistent quality.
