Review on 🔄 Enhanced Rotational Tester and AC Detector for Circulating Pumps and More by David Crowder

This is a handy little tool for showing energized solenoids and motors and motor rotation on some pump types. It is made in Sweden by Geonordic and seems to work well for the rotation indicator with Grundfos brand circulators but not so well with the Taco 007 series circulators. I don't know if this is due to the Taco motor's magnetic field being too weak or it is related to the amount of cast iron in the pump motor housing and flange. In larger systems with several pumps, e.g. B. in commercial boilers, this little tool makes it easy to tell when the pump motor is on when there is otherwise too much background noise or vibration from other nearby equipment to hear or feel if the motor is running. . To run. It also works to determine the rotation of small shaded pole motors used in things like bathroom fans. You can see and feel the small red and white disk inside the tester spinning as it is placed in the magnetic field. It was a bit pricey for such a small tool, and it may not always detect the magnetic field from every small motor, but it's still useful to have on your keychain.
