中文品名:手携式转速表
This tachometer indicates speed instantaneously and therefore enables speed fluctuations to be read off the dial. A circumference disc is provided to measure the circumference speed. 10 revolutions of this disc is equal to 1 mtr. So by dividing the number indicated on the gauge by 10, you can determine the number of revolutions per minute. When ordering, indicate the RPM capacity from the list below.
这款转速表可以即时显示速度,因此可以从刻度盘上读出速度波动。提供圆周圆盘来测量圆周速度。这个圆盘转10圈相当于1 mtr。因此,通过将仪表上显示的数字除以10,就可以确定每分钟的转数。订购时,请从下面的列表中注明RPM容量。
