UNI-T UT372 Tachometer
The UT372 features a compact and portable design, with body dimensions of 184x56x34mm and a weight of just 100g, making it exceptionally easy to handle and transport . Its housing, finished in a distinctive red and grey color scheme, is ergonomically shaped to provide a comfortable and secure grip during operation . Despite its lightweight construction, the device is built to be durable, suitable for use in various environments from workshops to production floors. The design focuses on practicality, with a clear LCD display prominently positioned for easy reading of measurements.
At the core of the UT372’s functionality is its non-contact optical measurement system, which utilizes a laser sight to accurately detect rotational movement without physical contact with the target object . This technology allows it to measure rotational speed across an impressive range from 10 to 99,999 RPM, covering both very slow and extremely fast rotations . The device operates by reflecting laser light off a small piece of reflective tape applied to the rotating object, calculating RPM based on the frequency of the reflected pulses. This method ensures minimal interference with the machinery being measured while providing highly accurate results.
The UT372 is designed with user convenience in mind, featuring an automatic power-off function that activates after approximately 15 minutes of inactivity to conserve battery life . Its operation is straightforward, allowing technicians to quickly obtain measurements by simply pointing the device at the target and pressing a button. The inclusion of a USB interface enhances its functionality, enabling connection to computers for data transfer and further analysis using the included software . This combination of features makes the UT372 not just a measurement tool, but a comprehensive solution for rotational speed monitoring and recording in professional settings.
