UNI-T UT371 Digital Laser Tachometer – Non-Contact RPM and Rotation Speed Meter

Description

Product Overview
The UNI-T UT371 is a handheld digital laser tachometer used to measure the rotational speed of machinery without making physical contact with the rotating part. The user places reflective tape on the target, directs the instrument’s optical sensor toward it, and reads the RPM value on the LCD.
Its non-contact measurement method makes it useful for routine inspection, preventive maintenance, and troubleshooting of rotating equipment. The counting function also allows users to count passing reflective objects within the instrument’s operating limits.

Usage and Compatibility Guidance
For accurate measurement, apply the supplied reflective tape to a clean, suitable target area on the rotating component. Keep the tachometer approximately 50–200 mm from the target, aim the optical sensor at the reflective mark, and follow the manufacturer’s operating instructions.
Keep hands, clothing, and test leads away from moving machinery. Do not attempt to touch or mark a rotating part while it is running. The reflective tape must be securely applied before operation, and the measurement distance and alignment should remain within the instrument’s specified limits.
