CMOS Simple Digital Timer School Physical Teaching Instrument With LED Display

Product information:

HT-J0202-1 simple timer is a digital instrument of measuring time, time interval, cycle and accumulative counting. It is mainly for school physical teaching experiment demonstration. It is together with HT-J2127 chute rail, free falling demonstration, simple pendulum experiment demonstrator and other mechanics laboratory apparatus supporting use. This timer machine adopts CMOS digital integrated circuit, LED digital display, direct and clear showing number and strong capacity of resisting disturbance.
