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 cooldown 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 Kaye’s Validator and traceable IRTD temperature standard. Features HTR and LTR Series Dry Wells CTR -80 Cryo Temperature Bath • Rapid response time with no oils or fluids • 120 minute cool-down from ambient to =80°C • Stability of ±0.02°C (±0.05°C for temperatures exceeding 300°C) • Stability of ±0.01°C • Very low noise • Lightweight yet rugged design for portability • Operates on standard line voltage • Operates on standard line voltage • Mounted on casters for portability • Dry well inserts minimize thermocouple tip cooling • Positions for two IRTD standards • Temperature range -95° to +140°C Amphenol Advanced Sensors CTR-80 Cryo Temperature Bath HTR and LTR Series Dry Wells Operating from -80 to 30°C, the CTR delivers fast response, high stability, and automated sensor calibration for the most severe cold-temperature applications. A generous one-gallon tank is heated and cooled quickly and quietly by a two-stage refrigeration (R507 and R508B). The CTR-80 is the ideal unit for calibrating temperature sensors used in freeze dryer, freezer, and cryo unit validation. The HTR and LTR Series dry wells are specifically designed for calibrating sensors used for process validation. These are the most advanced reference units on the market, featuring fast heat-up and cool-down, large well capacity to accommodate 18 to wr thermocouples, and use no messy oils or fluids. The HTR 400 is ideal for high-temperature applications such as autoclaves, dry heat ovens and sterilizer tunnels. The LTR models offer ultra low-temperature performance to -95°C for applications including freezers, cold rooms, incubators and autoclaves. The LTR model selection should be based on the application’s low-temperature point.
