Low temperature bath for charpy impact testing
Achieve precise and stable low-temperature conditions for accurate Charpy impact test results without the hazards of expendable refrigerants, ensuring reliable data in materials testing environments.

Controls Temperature for Charpy Impact Testing
The FTS CharpyCool™ Low Temperature Bath is an essential tool for research laboratories and materials testing facilities, specifically tailored for precise Charpy impact testing. This compact, benchtop unit excels in maintaining consistent temperature control from -80°C to +30°C, using mechanical refrigeration to bypass the need for liquid nitrogen or dry ice. It features a powerful variable speed magnetic stirrer for exceptional temperature uniformity, ensuring reproducible results. Accommodating up to 91 specimens within its 4 L or 8 L capacity, this solution is ideal for testing metals, polymers, ceramics, and composites. The CharpyCool exceeds ASTM Method E23 requirements, providing superior stability with ±0.1°C precision. Its digital temperature display and PID control deliver exact calibration, while its design minimizes hazards and costs associated with expendable refrigerants. Designed for easy integration into laboratory setups, the CharpyCool supports manual operations and offers engineering support for customized needs.
