Ideal for checking magnetic fields and the correct function of coils, such as relays and solenoid valves. The magnetic field detector is a non-contact device, so enclosures do not have to be opened. If a magnetic field is detected, the probe lights up a steady blue. The included permanent magnet is used to test the magnetic field detector before each measurement - Robust double enclosure, handy size with pocket clip, fits easily in any shirt pocket. - Build in torch with ON/OFF button - Supplied accessories: batteries and user manual. Magnetic fields: AC/DC; permanent magnet Detectable inductors: 63 H, 98 H, 401 H, 810 H (H = Henry) Operating voltage: 2 x 1.5 V AAA batteries Dimensions (W x D): 157 x 26 mm Weight: 50 g https://elecena.pl/product/18518316/p-1010-magnetic-field-tester 2021-05-20 https://elecena.pl/product/18518316/p-1010-magnetic-field-tester 2021-07-10 https://elecena.pl/product/18518316/p-1010-magnetic-field-tester 2023-01-04 https://elecena.pl/product/18518316/p-1010-magnetic-field-tester 2025-02-08 https://elecena.pl/product/18518316/p-1010-magnetic-field-tester 2025-09-06
