temperature standards stable uniform heat sources kaye temperature references are designed for easy operation while delivering the highest level of temperature stability possible. these stable uniform heat sources combine rapid heat-up and cool- down with large sensor capacity to minimize overall calibration time. multiple calibration set points are programmed via the easy-to-use operator panel and displayed (set point or well temperature) to 0.01 degree accuracy. these references provide fully automated sensor calibration when used with kayes validator and traceable irtd temperature standard. ctr -80 cryo temperature bath ? 120 minute cool-down from ambient to =80c ? stability of 0.01c ? very low noise ? operates on standard line voltage ? mounted on casters for portability ? positions for two irtd standards a mphenol advanced sensors features htr and ltr series dry wells ? rapid response time with no oils or fuids ? stability of 0.02c (0.05c for temperatures exceeding 300c) ? lightweight yet rugged design for portability ? operates on standard line voltage ? dry well inserts minimize thermocouple tip cooling ? temperature range -95 to +140c
