Bartington Cryogenic Magnetometers, CryoMag

These three-axis fluxgate magnetometers operate at temperatures down to 2K, making them ideal for use in cryostats for superconducting radio frequency cavities, quantum computing, and other ultra-low temperature environments.

These fluxgate magnetometers are available with a standard single probe, or with multiple sensor heads, all offering high precision measurement of static and alternating magnetic fields.

Features:

  • Operating temperature down to 2K
  • Noise level down to <20pTrms/√Hz at 1Hz
  • Frequency response from DC to 1kHz
  • Measuring ranges of ±70, ±100, ±250 and ±500µT
  • A single 3-axis probe, or 3 single-axis sensor heads

Typical Applications:

  • Magnetic field monitoring in cryostats and other low temperature environments
  • Use as feedback sensors in active magnetic field cancellation systems
