• Direct measurement of magnetic field strengths • Detects and measures the Earth’s magnetic field • Factory calibrated Hall-effect probe • 0-1V output for connection to data-loggers
This unit measures magnetic field strengths directly up to 2000mT (millitesla). Using a Hall-effect probe mounted on a rotatable ball and socket head, the Digital Magnetic Flux Density Meter can be used to investigate the fields around magnets and coils quantitatively and immediately.
The probe is permanently attached and is factory calibrated to the meter unit. The unit has 3 ranges
0-19.99, 0-199.9, and 0-1999mT selected by a 3 position switch. The LCD has 12mm digits, suitable for demonstration to small groups.
The multi-turn set-zero control can be used to compensate for unwanted background field. On the most sensitive range, the Earth’s magnetic field can be measured. As well as displaying the measured field strength on the LCD, a 0-1V output, proportional to the reading, is available at 4mm sockets for connection to a data-logger voltage sensor. Mass: 1.5kg. Size: 240 x 135 x 65mm.
Power by mains, with 250mA antisurge fuse. This device is compliant to EN61010-2010 with certificates available on request.

B. Circular Coil on Base
Circular Coil Mounted on a 10 x 7” Plastic base. A coil with 94 turns of 1 mm dia. Copper wire is mounted on a plastic base, and surrounds a plastic sheet on which iron fillings can be placed. Used to observe static magnetic fields generated by a constant flowing current. Iron Filings not included.
