The excellent properties of our Hall probes, including their high linearity and sensitivity, low and stable offset, wide operating temperature range, as well as high magnetic field operation, make them ideally suitable for use in a wide range of scientific, industrial and other applications. The cryogenic Hall probes are used primarily to measure strength, direction as well as relatively small changes in magnetic flux density. Several typical applications are shortly described below. More information should be found in scientific papers highlighted in the selected bibliography.


The accurate measurement of very high magnetic field in superconducting, hybrid or copper pulse magnets could be met using our LHP-N... or LHP-M... Hall probes. These models feature superior linearity and repeatability to other cryogenic models. Probes operate at a temperature range of 1.5 - 350 K in magnetic fields up to 30 Tesla. Their small overall dimensions make it ideally suited also for space-limited applications.


Analysis of the magnetic field above a superconducting tape using Hall probe is relatively simple non-destructive method. Several methods exist for the magnetic field mapping. Models HHP-V... allow to measure the perpendicular component of the magnetic field above a tape using movable XY positioner. Alike, the AXIS-3 Hall probe is suitable for the homogeneity studies of all three components of magnetic field produced by superconductor wires. MULTI-7 Hall arrays are adequate for monitoring the magnetic field profile near the surface of the multifilamentary tape. For the study on 2D self-field distribution in Ag-sheathed monofilamentary tape using a scanning magnetometry are suitable HHP-VP, VF, VA, SA or SF models. The homogeneity of the critical current of long superconducting tapes can be measured by contactless inductive method. The MULTI-7A Hall probe can be used to record the magnetic field produced by screening currents in a long YBCO tapes.


Possible approach for evaluating the behavior of grain boundaries in YBCO pellets is to measure the trapped flux by HHP-MA or HHP-MP Hall probe. Such measurement techniques are increasingly popular since they are non-destructive and may be applied to large samples. The HHP-VA or HHP-SF models are recommended for higher spatial resolution measurements.


Influence of current re-distribution on minimum quench energy of superconducting cable against local disturbance can be studied using HHP-MT or HHP-VC Hall probes.


Detection of small cracks in steel constructions coated by nonmagnetic paint is rapidly developing non-destructive technique. Scanning Hall-sensor microscope using HHP-VP or HHP-VA Hall probe is suitable to measure spontaneous magnetic field distribution in steels caused by a fatigue process.


As a standard, with Hall probe is supplied a data sheet with the following measured parameters:

  • sensitivity at 300 K and 0.2 Tesla
  • off-set voltage at 300 K and 77 K
  • change in sensitivity due to reversing of magnetic field
  • input and output resistances at 300 K and 77 K in a zero magnetic field
