VOLTCRAFT MS-440 Magnetic Field Tester

The Voltcraft MS-440 magnetic field tester is intended for detecting constant and alternating magnetic fields. The tester is ideal for testing the functioning of inductors carrying currents, such as relays, magnetic valves, etc. The MS-440 works with any contacts and, therefore, it is normally not necessary to open the casing.

If a magnet field is detected, the probe will light up and an acoustic signal will sound. A permanent test magnet, to test the functioning, is included in the delivery. The MS-440 has an integrated LED lamp.

* Supplied with MS-440 magnetic field tester, permanent test magnet, 2x AAA batteries and operating instructions
