Product Overview
Labotemp Cryogenic Test Chamber CTC-05 is a precision liquid nitrogen–cooled test chamber designed for controlled low-temperature impact testing of materials in accordance with international standards. Operating over a wide temperature range from +30°C to −196°C, the system is intended for specimen conditioning prior to pendulum impact tests (such as Charpy) where accurate temperature control is critical. The chamber applies a heat-balance circulation principle combined with forced air convection to ensure uniform cooling and stable specimen temperature before testing. Liquid nitrogen refrigeration enables rapid cooling, while digital temperature resolution of 0.1°C allows precise control during specimen conditioning. The chamber accommodates up to 60 specimens, supports independent sample loading without disturbing other specimens, and uses an imported cryogenic solenoid valve for stable cooling performance.

Key Benefits

• Ultra-low temperature capability down to −196°C for reliable specimen conditioning.
• Uniform cooling through circulating airflow and forced convection.
• Designed to meet international impact testing requirements for reproducible results.
• Single-specimen access without affecting remaining specimens.

Features

• Simple operation with a high-performance temperature control system.
• Liquid nitrogen refrigeration technology to achieve ultra-low temperatures down to −196°C.
• Designed in accordance with GB/T 229 Metal Charpy Pendulum Impact Test Method requirements.
• Heat-balance principle and forced circulation for uniform specimen cooling.
• Constructed entirely from stainless steel for durability and corrosion resistance.
• Circulating fan system to maintain consistent temperature distribution inside the chamber.
• Allows single-specimen sampling without affecting temperature stability of other specimens.
• Integrated imported cryogenic liquid nitrogen solenoid valve for reliable and controlled cooling.

Applications

• Specimen cooling and insulation for Charpy impact testing under ultra-low temperature conditions.
• Suitable for metallurgical laboratories, materials testing centers, quality control departments, and research institutions.
• Applicable to other low-temperature detection and testing requirements.
