Q1: Which devices are these magnetic test probes compatible with?
A1: The probe fits any standard 4mm banana plug magnetic socket, making it compatible with most multimeters, oscilloscopes, and power probes.
Q2: What is the advantage of a magnetic test probe over an alligator clip?
A2: Magnetic probes provide faster attachment, more stable contact, and are better suited for tight or confined spaces where alligator clips may slip or loosen.
Q3: Will the magnetic attachment affect testing accuracy?
A3: No. The magnet only provides fixation. The conductive parts ensure stable and accurate readings for both general-purpose and precision measurements.
Q4: What is magnetic testing, and how does it apply here?
A4: Magnetic testing uses magnetic force to establish secure, hands-free electrical contact. This probe accelerates testing, minimises human error, and ensures reliable readings in laboratories, automotive systems, and electronic projects.
Q5: Are the probes safe for industrial use and easy to operate?
A5: Yes. CE and RoHS certified, these probes meet international safety and environmental standards. No extra tools or soldering are needed—simply insert into any 4mm multimeter probe socket for instant use.
