Bartington is in the process of releasing a new three-axis cryogenic compatible sensor which has been tested in collaboration with CERN, the University of Uppsala and IPN Orsay during the development phase. The new Cryomag offers noise performance <20pTrms @1Hz, has 3 concurrent axes and a measuring range of 100µT (though additional ranges will be made available in the long term) and can easily connect to the new digitiser DG-1 which is also being released. This will allow for simple integration of the sensors with a USB output from the digitiser. A typical, 3-axis measurement setup including the digitiser will be less than $6000.
The first sensors are currently scheduled to ship at the beginning of April, with the main production expected to start from June 2020. [Update: Expected production Q1 2020].
