Digital Tachometer

Digital Tachometer
This digital tachometer is small, cost-effective display range is from 5-9999 RPM , it can accurately measure the RPM of the engine and various motors. My picture does not do justice to how clear the digits really are.
This unit works by gluing a small round magnet (supplied) to the rotating mass (flywheel) and attaching a small reed switch (supplied) to pick up the pulses. Mount the reed switch 5 to 25mm from the rotating magnet.
