Professional Non-Contact Speed Measurement
The UNI-T UT371 is a reliable non-contact optical laser tachometer designed for precise rotational speed (RPM) measurement and total revolution counting. Operating across an expansive measurement band from 10 RPM up to 99999 RPM and totalizing counts from 0 to 99999, this tool is indispensable for plant maintenance engineers, automotive technicians, and equipment inspectors. Non-contact measurement eliminates the safety risks and friction-induced loading errors associated with traditional contact tachometers, allowing safe evaluation of fast-moving turbine blades, belt drives, motor shafts, and rotating assemblies.
Advanced Optics and Flexible Operating Modes
Equipped with a high-visibility red laser pointer, the UT371 targets reflective markers attached to rotating machinery from distances between 50mm and 200mm. The instrument features a large 53mm x 41mm 5-digit LCD display capable of simultaneously showing rotational speed or accumulated counts alongside integrated clock timer information. Technicians can toggle between MAX, MIN, AVG, and real-time monitoring modes, alongside an adjustable sampling rate ranging from 0.5 to 255 seconds for tailored dynamic response during prolonged diagnostic sessions.
High Efficiency and Industrial Design
Engineered for field portability and extended battery performance, the UT371 delivers up to 40 hours of continuous operational runtime powered by four standard 1.5V AA alkaline batteries. Integrated low battery indication prompts the operator when supply voltage drops to or below 4.8V. Additional convenient functions include a power-saving auto-off feature set for approximately 15 minutes of inactivity (which can be disabled for long-term logging), data hold capability, and robust housing designed to endure harsh factory conditions.
Target Applications and Machinery Diagnostics
The UT371 non-contact tachometer is ideal for HVAC fan balancing, industrial motor speed verification, conveyor line speed calibration, generator output testing, and automotive engine pulley diagnostics. Its high-frequency pulse counter function accepts input signals up to 10kHz, rendering it equally useful for counting discrete items on automated assembly lines or measuring rapid optical pulses during sensor alignment routines.
