Model 475 DSP Gaussmeter

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.


  • Full-scale ranges from 35 mG to 350 kG
  • DC measurement resolution to 0.02 mG
  • Basic DC accuracy of ±0.05%

Model 410 Gaussmeter

This handheld gaussmeter is designed for accurate magnetic field measurements from 0.1 G to 20 kG (0.01 mT to 2 T). Most operating functions can be selected via the front-panel keypad with one or two keystrokes. The Model 410 displays in gauss or tesla, AC or DC values with resolution to 100 mG.


  • Ranges (Autoranging): ±200 G, ±2 kG, and ±20 kG ranges 
  • Frequency response: DC and 20 Hz to 10 kHz
  • Resolution to 3½ digits (1 part out of ±2000)
