Electro-magnet Probe Station

The ARS Electromagnet Closed Cycle Probe Station, PS-CC-EM, is designed for the ultimate flexibility for non-destructive device testing. This system provides a .6T Horizontal Magnetic Field and comes with a BiPolar Power Supply.

ARS manufactures both the cryocooler and the probe station. This integrated approach ensures consistent performance and also facilitates diagnostics and service of the integrated system.
