Digital tachometer for measuring the RPM of slot car motors. Also useful for measuring the RPM of any rotating object. Handy, practical and easy to use, it returns the exact motor RPM for a better evaluation of the motors to use in racing or for better matching between multiple motors. With the motor installed it is useful to assess any friction between the transmission parts. The package includes a handy zip case. For power it requires a 9V battery, not included.
It will be possible to buy the tachometer together with the mirror-paint marker, using the drop-down menu at the bottom of the description.
