The company's new HT-4100 hand-held tachometer is small, thin, and lightweight, weighing less than 4 oz. Measurement setup is reportedly as simple as applying a small piece of reflective tape marker or reflective paint to the surface of the object being measured. The tachometer's light beam has a range of 12 in, allowing measurements to be taken with an accuracy of 1 rpm. High rpm can be measured (up to 50,000 rpm) and indicated on a LCD display. The device continually displays the updated rpm every second. The last measured value is automatically held in memory for 1 min for easy verification and/or recording the measurement.
