UNI-T UT373 Mini Digital Laser Tachometer – Non-Contact RPM Speed Meter with LCD Backlight & Data Hold

Overview 

The UNI-T UT373 is a compact, highly reliable mini digital laser tachometer engineered for non-contact measurement of rotational speed (RPM) and total revolutions (COUNT). Utilizing advanced photoelectric sensing technology, the UT373 allows mechanics, engineers, and maintenance technicians to safely measure motor speeds, cooling fans, conveyor belts, lathe spindles, and rotating machinery from a safe distance using a visible laser beam. Housed in a pocket-friendly, ergonomic chassis with a clear backlit LCD screen, it delivers precision diagnostics for workshops on Hall Road and beyond.

Key Features 

• Non-Contact Laser Measurement: Safely measures rotational speed without requiring physical contact or mechanical linkages to moving parts.

• Wide RPM Measuring Range: Accurately detects speeds from 10.0 RPM up to 99,999 RPM with high-speed microprocessing sampling.

• Dual Measurement Modes: Easily toggle between RPM mode (revolutions per minute) and COUNT mode (total revolution pulse counting).

• High-Contrast Backlit LCD: Clear digital display with a bright white backlight for easy reading in dark industrial panels and machinery bays.

• Max/Min/Average Data Capture: Capture peak speeds, minimum drops, or average running velocities during operational testing.

• Pocket-Sized Ergonomics: Lightweight, compact body fits comfortably in one hand and stores easily in technician tool pouches.
