Model 475 DSP Gaussmeter

The Lake Shore combined the technical advantages of digital signal processing with over a decade of experience in precision magnetic field measurements to produce the first commercial digital signal processor (DSP) based Hall effect gaussmeter, the Model 475. DSP technology creates a solid foundation for accurate, stable, and repeatable field measurement while simultaneously enabling the gaussmeter to offer an unequaled set of useful measurement features. The Model 475 is intended for the most demanding DC and AC applications. In many cases, it provides the functionality of two or more instruments in a field measurement system.

Features

  • Full-scale ranges from 35 mG to 350 kG
  • DC measurement resolution to 0.02 mG
  • Basic DC accuracy of ±0.05%
  • DC to 50 kHz frequency range (probe-dependent)
  • 15 band-pass and 3 low-pass AC filters
  • Peak capture to 20 µs pulse widths
  • Data buffer sampling rates to 1000 readings per s
  • Computer interface sampling rates to 100 new readings per s
  • Integrated electromagnet field control algorithm
  • Standard probe included
  • Specialized and custom probes available
  • CE mark certification
