Calibration calibration bath LN2

ultra-low-temperatureportableimmersion

Product
KAYE LN2 Comparator (KG-300) liquid nitrogen bath for semi-automated calibrations at approximately -196°C. Designed for use with KAYE Validators and Kaye IRTD, the unit enables stable, long-duration calibrations at ultra-low temperature with low LN2 evaporation. The included thermocouple fixture holds up to 48 thermocouples and centers the IRTD within the calibration block.

Features

• Semi-automated thermocouple calibration support when paired with KAYE Validators
• Stainless-steel Dewar for safe operation and durability
• Thermocouple holder for up to 48 thermocouples
• Kaye IRTD mounting at block center for repeatable measurements
• Easy-fill port for controlled LN2 replenishment
• Low evaporation design for stable calibration points over several hours
• Foam lid to reduce LN2 evaporation between runs
• Rugged wheeled transport case for storage and mobility

Applications

• Ultra-low temperature freezers
• LN2 freezers
