Designed to meet the demanding needs of the permanent magnet industry, the
Lake Shore Model 425 gaussmeter provides high end functionality and performance
in an affordable desktop instrument. Magnet testing and sorting have never been
easier. When used in combination with the built in relay and audible alarm features,
the Model 425 takes the guesswork out of pass/fail criteria. Additional features
including DC to 10 kHz AC frequency response, max hold and relative measurement
make the Model 425 the ideal tool for your manufacturing, quality control and R&D
flux density measurement applications. For added functionality and value, the
Model 425 also includes a standard Lake Shore Hall probe. Put the Model 425 gauss-
meter to use with confidence knowing it’s supported by the industry leading experts
in magnet measurement instrument, sensor and Hall probe technology.
1.1.1 Throughput
Throughput involves much more than just the update rate of an instrument. An intui-
tive menu navigation and keypad, along with overall ease of use are equally impor-
tant. The Model 425 is designed with these qualities in mind. The operation is
straightforward, with user display prompts to aid set-up. We understand that time is
money! In addition to being user friendly, the automated magnet testing and sorting
features of the Model 425 streamline sorting and testing operations. In addition, hot
swapping of Hall probes allows you to switch probe types without powering the
instrument off and back on. These features support increased productivity, allowing
you to spend less time setting up your instrument and more time working on the task
at hand.
