Product Overview
The UNI-T UT371 is a digital non-contact tachometer designed to measure the rotational speed and count of rotating shafts, disks and other moving objects. Using optical laser detection and reflective tape, it measures rotational speeds from 10 to 99,999 RPM and supports counting from 0 to 99,999 without physical contact with the target. The instrument features a five-digit LCD, MAX/MIN/AVG measurement modes, data hold, adjustable sampling rate and switchable laser operation. Its measurement distance is 50–200mm. Powered by four 1.5V AA batteries, the compact UT371 is suitable for portable rotational speed inspection and maintenance applications. Please note that USB communication and PC software are features of the UT372 model, not the UT371.
