4D Hall Probes


	Hall Probes for MG-4D/5D Gaussmeters

		A wide selection of transverse and axial Hall probes is available to meet most applications. Accuracy of measurement is assured through the use of pre-calibrated probes which are calibrated in high accuracy fields standardized by nuclear magnetic resonance techniques which permit traceability to the National Institute of Standards and Technology (NIST). Probes are available with accuracies from ±0.1% to ±1.5% of reading. These probes are directly interchangeable and do not require special calibration. All probes are quickly self-calibrated to their instrument via a convenient front panel control. The transverse Hall probe measures magnetic fields perpendicular to the axis of the probe. Standard probe thicknesses range from a thin-line version of .043" (1.09 mm) to a ruggedized version of 0.063" (1.60 mm). Ultra-thin probes are available on special order. The axial Hall probe measures magnetic fields parallel to the axis of the probe such as solenoidal fields. Standard probe stem diameters are .263" (6.68mm) and are housed in a rigid plastic stem for maximum protection for the most demanding industrial and laboratory applications. This instrument is supplied with a 6-foot probe cable. However, additional cable length can be ordered as an option. Assistance is available to help in selecting the most suitable probe for your application.
