More info


A simple tachometer equipped with a contactless reflection sensor built on the basis of a transmitting diode and phototransistor operating in the infrared band. The device allows you to easily measure the speed of the rotated objects, eg wheels or drive shafts. It is enough to apply a white point to the object to be measured, so that the diode light reflected from it falls on the phototransistor.
