Klinger Scientific Teslameter Digital 

The teslameter is used for the measurement of flux densities in steady magnetic fields. The unit includes a Hall sensor probe for measuring axial and tangential magnetic fields up to 20mT. The magnetic field probe is provided with a metric scale for measuring distances. In addition to having a digital display, the unit outputs a voltage proportional to the magnetic field which can be measured with a data logger, XY-recorder or analogue multimeter.
