Short Description

The Lutron DT-2234C is a professional non-contact digital tachometer designed to accurately measure the rotational speed (RPM) of motors, shafts, gears, fans, pulleys, and other rotating machinery without physical contact. Using a precision optical laser sensor and reflective tape, it provides fast, reliable measurements over a wide RPM range. Its large LCD display, memory recall, automatic range selection, and rugged ABS construction make it ideal for industrial maintenance, quality control, laboratories, automotive workshops, and manufacturing applications.
