Testboy Magnetic field testers

Highest quality & accuracy

Testboy magnetic field testers work without contact and are perfect for checking solenoid valves and switches. They work quickly and precisely, and their illuminated tip indicates all permanent, DC and AC magnetic fields. Their sensitivity makes it possible to carry out the test without having to remove the casing or cover of the object being tested. The magnetic field tester can perform the function test even during operation, without any set-up time and without stopping the machine or device. Testboy magnetic field testers detect and check magnetic fields in hydraulic and pneumatic systems and offer a test function for relays, solenoid coils, valves, pumps and contactors. This tells you immediately and unambiguously whether they are still working properly. How else could you reliably test whether a solenoid valve that looks intact from the outside might be the cause of a malfunction? Magnetic field testers provide the answer! They are used in heating and plumbing, in car workshops and in industry, and thanks to their compact dimensions they are a constant companion that fits in a shirt or trouser pocket.
