Model 701-3/31 Superconducting Quantum Interference Device (SQUID) magnetometer from Tristan Technologies of San Diego, California. This instrument is used for nondestructive characterization of non-ferromagnetic materials.  The heart of the system is a High-Temperature Superconducting (HTS) SQUID magnetometer that offers 100 fT/Hz^1/2 noise threshold at 3 mm coil size.
