The Challenge: Diagnosing Rotating Equipment Without the Right Tools

When a conveyor belt starts slipping, a fan isn’t moving enough air, or a motor sounds different than yesterday, maintenance technicians need answers fast. Guessing at rotational speeds leads to misdiagnosis, unnecessary parts replacements, and equipment that fails again within weeks.

Traditional tachometers force you to choose: either a contact model that requires risky close-up measurements, or a non-contact unit that struggles with dirty environments and reflective targets. In Australian industrial settings—where dust, heat, and harsh conditions are standard—you need an instrument that adapts to the situation at hand.

The Solution: One Tachometer, Two Measurement Methods

The REED R7110 eliminates compromise by combining precision laser-guided optical measurement with reliable mechanical contact readings in a single, rugged instrument. Whether you’re checking shaft speeds from a safe distance or verifying belt velocity through direct contact, the R7110 delivers accurate results you can trust.

The Class II laser provides exceptional targeting accuracy at distance, while the included adapter kit handles everything from small motor shafts to wide conveyor belts. With a measurement accuracy of ±0.02% plus one digit, you’re getting laboratory-grade precision in a handheld package designed for real-world conditions.

Key Advantages for Australian Trade Professionals

Dual-Mode Flexibility Switch seamlessly between non-contact laser readings (1 to 99,999 RPM) and contact measurements (1 to 19,999 RPM) depending on your access, safety requirements, and environmental conditions. The R7110 adapts to your workflow—not the other way around.

Enhanced Display Visibility The backlit, rotatable LCD screen delivers clear readings in low-light switchrooms, bright outdoor settings, or awkward positions where standard displays would be unreadable. Five-digit resolution ensures you capture precise measurements without squinting or repositioning.

Comprehensive Memory Functions Store the last 10 readings plus maximum, minimum, and average values. This built-in data logging proves invaluable when establishing baseline equipment performance, documenting maintenance activities, or comparing readings over time to spot developing problems.

Complete Accessory Package Arrive on site fully equipped with large and small wheel adapters, cone adapter, funnel adapter, reflective tape, batteries, and protective carrying case. No additional purchases required—just unpack and start measuring.

Extended Battery Life Approximately 20 hours of operation from three AAA batteries means the R7110 handles multiple service calls between battery changes. The low battery indicator ensures you’re never caught short during critical measurements.

Built for Australian Industrial Conditions

Operating reliably from 0°C to 50°C, the R7110 performs across the temperature extremes encountered in Australian facilities—from air-conditioned control rooms to un-cooled warehouses in summer. The compact 176 × 63 × 38mm dimensions and 181g weight make it easy to carry in your tool belt or keep accessible in your service vehicle.

CE, UKCA, and RoHS certifications confirm compliance with international safety and environmental standards, while the optional tripod mount supports extended monitoring applications.

Trouble-shooting Procedures

Reflective Marking Tape To use this, simply cut the adhesive tape provided into approximately 12mm ( 0.5″) squares, peel off the backing and apply one square to each rotation shaft. The non-reflective area must always be greater than the reflective area. If the shaft is normally reflective, it must be covered with black tape or black paint before attaching the reflective tape. The shaft surface must be clean and smooth before applying the reflective tape.

Very Low RPM Measurements

When measuring very low RPM values, it is recommended to attach more reflective tape and take several readings. Divide up all the readings taken to come up with an average RPM measurement.
