Frequently Asked Questions
Q: What does this solenoid coil tester actually do?
A: The solenoid coil tester detects the presence and direction of a magnetic field generated by solenoid coils in circulation pumps, oil burners, and other electrical components. By using its red-white screw rotation indicator, technicians can instantly confirm whether a pump coil is energised and which direction it is rotating — without disassembling the unit.
Q: Does the solenoid coil tester require batteries?
A: No batteries are required. The tester operates passively by responding to the magnetic field of the solenoid coil it is placed near, making it a maintenance-free, always-ready diagnostic tool.
Q: Is this tester suitable for home use, or is it only for professionals?
A: This tester is designed for both home and commercial use. Its simple operation and compact key ring form factor make it accessible for DIY homeowners checking their own heating systems, as well as professional plumbers and HVAC technicians needing a reliable on-the-go tool.
Q: Which systems is this solenoid tester compatible with?
A: It is compatible with a wide range of heating circulation pumps, oil burner solenoids, and general electrical coil components found in residential and commercial heating, refrigeration, and industrial maintenance systems.
