Fluke 930 Non-Contact Tachometer
The Fluke 930 is a handheld non-contact optical tachometer designed to measure the rotational speed of rotating equipment without physical contact. It is particularly useful when direct contact with a rotating shaft, fan, motor or other moving component is impractical or unsafe.
The Fluke 930 uses optical sensing to measure rotational speed from 1 to 99,999 RPM with an accuracy of ±0.02% of reading + 1. Its compact design and backlit display make it suitable for routine field measurements and equipment maintenance.

Fluke 930 vs Fluke 931
The Fluke 930 is the non-contact configuration, while the Fluke 931 adds contact measurement capability.
The Fluke 930 should therefore be positioned specifically as a non-contact tachometer, rather than as a combination contact/non-contact tachometer. Fluke's specifications list contact measurement from 1 to 19,999 RPM for the 931, not the 930.
FAQ
What is the measurement range of the Fluke 930?
The Fluke 930 measures rotational speed from 1 to 99,999 RPM using optical non-contact measurement.
Is the Fluke 930 a contact tachometer?
No. The Fluke 930 is designed for non-contact optical measurement. Contact measurement is available on the Fluke 931, not the 930.
What is the accuracy of the Fluke 930?
The specified accuracy is ±0.02% of reading + 1.
How far can the Fluke 930 measure from the rotating target?
The specified optical sensing distance is 500 mm.
What industries can use the Fluke 930?
It is suitable for machinery maintenance and troubleshooting in manufacturing, automotive, textile, pulp and paper, metalworking, chemical manufacturing, water treatment and HVAC applications.
