This Digital Magnetic Flux Density Unit measures magnetic field strengths directly up to 100mT (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 surrounding magnets and coils quantitatively and immediately; without using indirect methods such as flux coils and ballistic galvanometers. 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; which cover most laboratory requirements.
The 3½ digit LCD display (digit height 12mm) features automatically set decimal point. The sensitive multi-turn set-zero control can be used to compensate for unwanted background fields. Note that on the most sensitive range; the Earth's magnetic field can be measured.
As well as displaying the measured field strength on the LCD display; a p.d. from 0-1V; proportional to the reading; is available at 4mm sockets for connection to a data-logger of input resistance greater than 100kΩ.
