TACHYMETER

TACHYMETER

The tachymeter is the device which measures the speed of an automobile. Knowing is how many seconds the car covers a distance of 1Km the meter can measure the approximate average speed per hour during a journey [up to the maximum measurable range of tachymeter is 60 seconds].
If the chronograph is started at the same time as measurement, and stopped after 1 Km, the average speed per hour can be determined according to the position of the second hand.
- If the car covers the distance of 1 Km in 45 seconds, the average hourly speed during the journey will be about 80 Km.
