The UNI-T UT373 non-contact tachometer is a reliable tool for measuring the speed of engines and other machines, providing safe and accurate results without the need to come into contact with a rotating object. The device allows measurement in units of revolutions, offers automatic range selection and displays values ​​up to 99999 with an overload ("OL") function. UT373 has Max/Min functions, result retention (Data Hold), active measurement signal (Signal Trigger/Laser-On), as well as low battery indicator and automatic shutdown. The backlit LCD display ensures readability in all operating conditions, and CE and UKCA certificates attest to high quality and safety standards.

Functionality that makes everyday work easier
The UT373 is designed to be quick and easy to use - automatic range selection allows for immediate accurate results, and Max/Min functions help control extreme values during tests. The data storage function allows you to conveniently save the result on the display, which is extremely useful when analyzing the measurements. The tachometer indicates laser activity and low battery status, ensuring smooth operation without unnecessary interruptions.

Robust design and comfortable use
The UNI-T UT373 has a lightweight, ergonomic design and the robustness needed in industrial and workshop environments. Thanks to the backlit LCD display, results can be read even in dimly lit rooms. Automatically turning off the device after inactivity helps save energy and extend battery life. The UT373 is the ideal solution for professionals who value safety, accuracy and comfort every day.
