Description

F.W. Bell 620 Gaussmeter STB4-0404 Hall Probe Gauss Meter Magnetic Field

The F.W. Bell Model 620 is an analog benchtop/portable gaussmeter designed to measure DC and AC magnetic field strength using an interchangeable Hall effect probe. It features a moving-coil analog meter display with multiple full-scale ranges, probe zero and probe range controls, and both AC mains and battery-backup operation. This unit includes the F.W. Bell STB4-0404 Hall effect probe with cable and the original foam-lined probe storage case.

Specifications & What's Included

  • Make / Model: F.W. Bell Model 620 Gaussmeter
  • Display: Analog moving-coil needle meter with multiple full-scale ranges (visible range selector knob on front panel)
  • Measurement type: DC/AC magnetic field (Gauss / Tesla)
  • Probe included: F.W. Bell STB4-0404 Hall effect probe with black cable; labeled
    Condition: For Parts or Not Working
    This F.W. Bell Model 620 Gaussmeter powers on and the analog needle responds to magnetic fields, but we were unable to calibrate the instrument and are selling it as-is with no functionality guarantee. It is being sold for parts, repair, or as a donor unit for someone with the calibration equipment to bring it into spec. The unit includes the F.W. Bell STB4-0404 Hall effect probe with cable and original foam-lined probe storage case. Cosmetically the instrument appears in good shape with normal age-related wear on the chassis. Please view our photo set and contact us if you have any questions.
