UNI-T UT373 | Mini Tachometer

The UNI-T UT373 Mini Tachometer is a compact, non-contact RPM meter for measuring the rotational speed of motors, fans, shafts, and machines using laser-based optical sensing. It displays RPM (revolution count) and allows safe speed checking without touching moving parts. UNI-T lists UT373 with 10.0–99,999RPM measurement, 0–99,999 count range, auto range, MAX/MIN, data hold, laser-on indication, LCD backlight, 50–200mm target distance and ±30° measuring angle from perpendicular.

Pro Tip

Keep the meter close to perpendicular to the reflective tape; excessive angle can weaken the reflected signal and disturb the RPM reading. Buy UNI-T UT373 from Kamadi Pakistan for compact non-contact RPM measurement.

Buyer’s Selection Guide

Choose the UT373 if you need a small, economical non-contact tachometer for RPM and count measurement. For USB or contact-wheel functions, compare with UT372 or UT372D.
