Impact Specimen Cooling Temperature Chamber – NG-ISCC Series
The NG-ISCC Low Temperature Chamber is built to cool and stabilize Charpy impact specimens before testing. It supports conditioning from +30°C down to -60°C, -80°C, -100°C, or -196°C depending on the model. NG-ISCC-60 and NG-ISCC-80 use compressor-based refrigeration, while NG-ISCC-100 and NG-ISCC-196 use liquid nitrogen cooling to achieve ultra-low setpoints. Temperature control accuracy is ≤ ±0.5°C with a 0.01°C instrument resolution, using ethanol or another non-freezing solution as the cooling medium. It is widely used in materials testing and quality control programs to evaluate low-temperature toughness of metals and alloys.
