Precise temperature control of impact specimens
SP Scientific
CharpyCool is a low temperature bath that provides metallurgists with a wider range of temperature control.
The new CharpyCool is a mechanically refrigerated bench top bath that eliminates the need for costly consumables such as liquid nitrogen or dry ice.
It offers up to 8 liters of working fluid volume enabling up to 91 Charpy impact test specimens to be accommodated at temperatures between -80°C and 30°C.
Features and benefits include:
- A powerful variable speed magnetic stirrer and vortex breaker provide temperature uniformity and stability.
- 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 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.
