UNI-T UT371 non-contact tachometer

The Uni-T UT371 is a non-contact tachometer that measures rotational speeds from 10 to 99,999 RPM. It uses a laser and reflective tape to take readings without interfering with the machine being tested. The device also offers a counting function from 0 to 99,999 and works at a distance of 50 to 200 mm. Accuracy ranges from ±0.03% to ±(0.04% + 2), depending on the measurement range.

The five-digit LCD shows speed and time at the same time, so results can be followed in real time. MAX, MIN, AVG and Standard modes make it easier to spot speed changes and compare readings without further calculation. The adjustable sampling rate of 0.5 to 255 seconds lets you tailor the instrument to your application. Data hold, automatic shut-off after about 15 minutes and a low-battery indicator complete the feature set.

The compact housing measures 184 × 56 × 34 mm and weighs 100 g, making it easy to carry on site. Contactless measurement is useful for maintenance, diagnostics and monitoring rotating equipment.
