UNI-T UT373 non-contact tachometer

The UNI-T UT373 non-contact tachometer is a reliable tool for measuring the speed of motors and other machines, providing safe and precise results without the need for contact with a rotating object. The device allows measurement in RPM units, offering automatic range selection and displaying values up to 99999, with an overload ("OL") indication function. The UT373 features Max/Min functions, result retention (Data Hold), active measurement indication (Signal Trigger/Laser-On), as well as a low charge indicator and automatic shutdown. The backlit LCD display ensures readability in all operating conditions, and CE and UKCA certifications confirm high quality and safety standards.

Functionality that makes everyday work easier

The UT373 is designed for quick and easy operation - automatic range selection allows for instant accurate results, and Max/Min functions help monitor extreme values during tests. The data retention function allows you to conveniently save the result on the display, which is extremely useful when analyzing measurements. The tachometer indicates laser activity and low charge status, ensuring uninterrupted operation without unnecessary interruptions.

Robust design and convenience of use

The UNI-T UT373 features a lightweight, ergonomic design and the ruggedness necessary for industrial and workshop environments. Thanks to the backlit LCD display, reading the results is possible even in dimly lit areas. Automatic shutdown of the device after a period of inactivity helps save energy and prolongs battery life.
