Defintion :
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. The Model 475 is intended for the most demanding DC and AC applications.
Lakeshore also offer Model 460 3-channel Hall effect gaussmeter which is the best choice for applications requiring 3-axis measurements or 3 simultaneous single axis measurements. The Model 460 combines the performance of 3 Model 450 gaussmeters into one package, making it an excellent value for materials analysis and field mapping applications. The large vacuum fluorescent display shows readings for all 3 channels simultaneously as well as vector magnitude or differential readings. The full-function keypad provides easy access to measurement features
