It is used by plant engineers and maintenance technicians to check RPM on motors, shafts, and conveyor systems across industrial facilities, including machining, material handling, and pump applications.

What are the specifications of the REED INSTRUMENTS R7140 tachometer?

The REED INSTRUMENTS R7140 offers RPM accuracy of +/-0.05% of Reading +1 Digit and RPM resolution of 0.1 RPM. It features an LCD digital display and includes a funnel adapter. A calibration certificate is not included. The manufacturer part number is R7140.

Where to buy the REED INSTRUMENTS R7140 combination tachometer worldwide?

3G Electric supplies the REED INSTRUMENTS R7140 combination tachometer to customers worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your facility. Contact us for availability and lead time on this precision measurement instrument.

How to select between contact and non-contact tachometer modes on the REED R7140?

Use non-contact mode for safe, remote RPM measurement of rotating parts you cannot touch, such as high-speed shafts or exposed blades. Use contact mode with the included funnel adapter for direct measurement on low-speed shafts or where optical access is blocked. The REED R7140 switches between both modes easily.
