The 2G-Entreprises SRM has a measurement sensitivity of 10-12 Am2 and an exceptionally wide dynamic range of 10-12 to 10-4 Am2. This property enables measurements of a broad array of natural magnetic materials, from extremely weak magnetic particles (such as micrometer scale dust particles) to strong natural magnets (such as volcanic rocks).

The 2G-Entreprises SRM employs three orthogonal DC-SQUIDs (Superconducting Quantum Interference Device) to achieve the desired sensitivity and dynamic range. The SQUIDs are hosted in a magnetically clean chamber produced from high magnetic permeability Ni-Fe alloy (MuMetal). An additional superconducting circuit is used to attenuate residual magnetic noises. The superconducting circuits operate in cryogenic temperature of 4K, achieved by liquid helium dewar.

The system includes an automatic computer-controlled sample handler and an in-line Alternating Field (AF) demagnetization coils, and ARM system protected by three layers of MuMetal shields. It is designed to perform almost all the basic paleomagnetic procedures in the most sensitive, reproducible, and time-effective manner.
