Product Model:
PS-Cryo

Product Introduction:
The PS-Cryo closed-loop 4 K cryogenic probe station uses a GM refrigeration mechanism, requiring no consumable liquid helium, providing 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 systematized, software operation allows one-click temperature control and electrical testing, making it the most cost-effective choice for cryogenic electrical testing.
