It can be used for demonstrative and students group experimentsin physics, such as, measuring time, period, count etc. The digital timer is surveys the time-gap one kind of precise digital measuring appliance,is feeds specially the school physics teaching the demonstration performanceand the survey time and so on the experimental one kind of general instrument,also available in the counting, measures the cycle, general and air cushionguide rail necessary use.The this aircraft besides the power source and the photoelectricity transformation,uses the CMOS double row in-line type digital integrated circuitto use the quartz crystal oscillator to take the time base signal, the time precisionis high; Uses the LED nixietube demonstration data, the reading is clear;Uses two printed wiring board compact, the structure, the contact is good; Usesthe ABS engineering plastics engine case, the elegant appearance and has is advantageousfor merits and so on overhaul, debugging.
