Precise Temperature Control of Impact Specimens

SP Scientific has introduced the CharpyCool, a low temperature bath that provides metallurgists and testing laboratories a wider range of precise temperature control for impact specimens cooling, with one of the smallest footprints on the market.

The new CharpyCool is a mechanically refrigerated bench top bath that eliminates the need for costly consumables such as liquid nitrogen or dry ice. Compact and completely self-contained, the CharpyCool offers up to 8 litres of working fluid volume enabling up to 91 Charpy impact test specimens to be accommodated at temperatures between -80°C and +30°C. A powerful variable speed magnetic stirrer and vortex breaker provide excellent temperature uniformity and stability enabling superior results. PID control enables the CharpyCool to sustain precise temperature control to within ± 0.1°C. The CharpyCool includes a digital temperature display, and an optional Charpy Rack is available which allows multiple-specimen loading and easy access to monitor your testing.

The CharpyCool exceeds the strict temperature stability requirements of the American Society for Testing & Materials (ASTM) Method E23 for charpy impact testing, a standardised high strain-rate test, most often used on metals, polymers, ceramics and composites used to determine the amount of energy absorbed by a material during fracture. This absorbed energy is a measure of a given material's toughness and acts as a tool to study temperature-dependent ductile-brittle transition.
