2.5 Temperature Reference
Temperature references provide the stable temperature required for sensor calibration.
Six temperature reference models are available. They are designed to provide different
temperature ranges and are compatible with the Validator AVS.
LTR-90 (setpoint range -95°C to 140°C at 23°C ambient)
Recommended for calibration of sensors used in freeze dryers, freezers, cryogenic units,
incubators and steam autoclaves. The LTR-90 accepts up to 12 thermocouples
LTR -25/140 (setpoint range -25°C to 140°C at 25°C ambient)
Recommended for calibration of sensors used in freezers, cold rooms, incubators and steam
autoclaves. The LTR -25/140 accepts up to 18 thermocouples.
LTR -40/140 (setpoint range -40°C to 140°C at 25°C ambient)
Recommended for calibration of sensors used in freezers, cold rooms, incubators and steam
autoclaves. The LTR -40/140 accepts up to 18 thermocouples.
HTR 400 (setpoint range 25°C above ambient to 400°C)
Recommended for calibration of sensors used in steam autoclaves, dry heat ovens and
tunnel sterilizers. The HTR 400 accepts up to 24 thermocouples.
CTR -80 (setpoint range -80°C to 30°C)
Recommended for calibration of sensors used in freeze dryers, freezers, and cryogenic units.
The CTR -80 accepts up to 36 thermocouples.
CTR -40 (setpoint range -40°C to 150°C)
Recommended for calibration of sensors used in freezers, cold rooms, incubators and steam
autoclaves. The CTR -40 accepts up to 36 thermocouples.
