RPM measurement Kit #2


Speed measurement tool for conventional motors

Advanced multimeter and attachment kit for kits #15-17 or many other similar designs where wire coil rotates in the static magnetic field.

Attachment comes as a kit but could be assembled in minutes – no special tools required.

The RPM measurement tool is based on frequency measurement. Advanced multimeter could be also used for all other measurements in your experiments and beyond.

If you already have a multimeter that can measure the frequency in Hz you might be interested in a standalone RPM measurement attachment.

Please note that for all brushless motors on our site (kits #1-9, 11-14) you should choose RPM measurement tool #1 (either as a complete kit or an attachment).

Requires one standard 9 Volts battery and four AA batteries (not included).
