Lake Shore Cryotronics Exhibiting at The Magnetics Show North America

Lake Shore Cryotronics will be discussing its high-performance magnetic measurement and control instruments at The Magnetics Show North America in Pasadena, CA next week.

The company will be in Booth 602 demonstrating measurements specifically performed using its award-winning F71 teslameter with its compatible 3-axis FP Series Hall probe as well as the Model 480 fluxmeter with a 2.5-inch Helmholtz coil featuring a field strength of ≈30 G/A.

The teslameter, which is also available in a single-axis (F41) version, offers:

  • Fast, worry-free, and highly accurate field measurements
  • Live plotting that allows one to easily see fields changing over time
  • High-speed pulse detection with the addition of maximum peak holding
  • Fully configurable digital low-pass, high-pass, and bandpass filters
  • TruZero™ technology that eliminates any need to re-zero the attached Hall probes

Both teslameter versions can be integrated easily into a cryogenic system. They feature built-in external source temperature compensation and a cryogenic mode, which reduces power dissipation into the compatible cryogenic-rated Hall probe/sensor by orders of magnitude when measuring below 4 K (as explained in this "Magnetic Field Measurement at Cryogenic Temperatures" application note).

The Model 480 fluxmeter is ideal for magnetizing, manual and automated magnet testing and sorting, and use as the main component in BH loop or hysteresis measurement system applications. It features:

  • Automatic drift compensation
  • Very fast peak capture
  • AC frequency response to 50 kHz
  • 5¾ digit DC resolution (1 part out of ±300,000)
  • Storage of parameters for up to 10 existing coils
