The magnetic field strength meter FH 55 is a compact benchtop instrument for measuring the magnetic field strength H in Ampere per Meter (A/m) and the magnetic flux density or induction B in Tesla (T) or Gauss (G). Particular features of the FH 55 are high accuracy, easy handling and a multitude of functions. Apart from the possibility of measuring static (DC) or alternating (AC) fields, the FH 55 offers many functions, e.g. manual or automatic range selection, maximum and minimum value storage and adjustable limit values with relay output. The relative function can be used to show the difference to a set value or to measure small changes in a large magnetic field. A special feature of the FH 55 is the Peak Hold function. This enables the maximum values of even very short magnetizing impulses to be recorded. The FH 55 has an analog output and a computer interface that allows data transfer and remote operation. The handy, well-designed foil keyboard protects the inside of the instrument from dirt. All important functions are available at the touch of a key. Relative and limit values can be easily entered via the numerical keypad. Many different Hall probes are available, for example probes with especially small active areas for measurements at the size of a dot, or probes with a high sensitivity or with a built-in sensor for correction of temperature dependency. The latter also allow a display of the temperature. More details can be found in the probe data sheet.
