About
CryoMag three-axis fluxgate magnetometers are perfect for operation at temperatures as low as 2K, making them the ideal choice for use in cryostats for superconducting radio frequency (SRF) cavities, quantum computing, and other ultra-low temperature environments. These fluxgate magnetometers are available with a standard single probe or multiple sensor heads, all offering high precision measurement of static and alternating magnetic fields. Key features include an operating temperature down to 2K, noise level down to <20pTrms/√Hz at 1Hz, and a frequency response from DC to 1kHz. They offer measuring ranges of ±70, ±100, ±250 and ±500μT, and are available as a 3-axis probe or with 3 single-axis sensor heads (CryoMag-IE). Applications include magnetic field monitoring in cryostats and other low temperature environments, as well as use as feedback sensors in active magnetic field cancellation systems.
