Press Release Summary:
Offering alternative to argon triple point and other cryogenic calibrators, Cryo-Cal® utilizes phase change point of liquid nitrogen to establish reference temperature of approximately -196°C or 77 K. Four Teflon® lined bushings guide sensors into gold-plated equalization block, which resists corrosion and oxidation and contributes to 0.002 K stability and uniformity. With no moving parts or pumps, Cryo-Cal is virtually maintenance-free.
Original Press Release:
CRYO-CAL
CRYO-CAL-1 is an alternative to the argon triple point and other cryogenic calibrators. The Cryo-Cal® utilizes the phase change point of liquid nitrogen to establish a reference temperature of approximately -196°C or 77K. There are four Teflon® lined bushings that guide sensors into the gold plated equalization block. It is completely immersed in the cryogenic liquid contained within a super-insulated vacuum dewar. Cryo-Cal's gold plated equalization block greatly reduces corrosion and oxidation and contributes to 0.002 K stability and uniformity of the whole system.
