The Cryogenic Probe Station, PS-Cryo, is a closed-loop 4 K system with a GM refrigeration mechanism. This requires no consumable liquid helium and provides a low-temperature environment down to 4 K. It can accommodate 2-inch samples and meets standard I-V, C-V, microwave, and optoelectronic testing needs.
Highly integrated and systematised, the software operation allows one-click temperature control and electrical testing, making it the most cost-effective choice for cryogenic electrical testing.
