Assembled Digital RPM Counter
Assembly of the RPM counter from the kit requires certain skills and experience with soldering. This task might be too challenging for a beginner. You may order 3 digit counter preassembled for an additional fee. It comes with instructions on how to use it for motor speed measurement. Battery is included.
This is preassembled ready to use device. Please note that original digital counter kit was developed by another company and therefore we do not provide any additional technical support besides its use for RPM measurement.
