Product overview
Labotemp Cryogenic Test Chamber CTC-04 is a high-capacity cryogenic chamber designed for ultra-low temperature testing using liquid nitrogen refrigeration. It operates as a temperature test chamber, thermal chamber and environmental test chamber, providing uniform cooling for specimen freezing, insulation testing and low-temperature impact evaluation. The chamber reaches a minimum operating temperature of -190°C and is suitable for research, materials testing and industrial low-temperature applications. It uses a heat-balance circulation mixing method to ensure temperature uniformity. The interior is 304 stainless steel with 160 mm fireproof perlite insulation. USB data output and tray-based loading enable accurate monitoring and repeatable testing.
