Digital Pressure GaugeImpact Testing Machine
Impact Testing Machine
Features
- Suitable for Charpy and Izod Impact Tests on various materials.
- Rigid designs of machine frame and other parts assure minimum energy absorption during fracture which results in improved test accuracies.
- The highly stressed and wearing parts like support blocks and striker are of special alloy steel duly heat treated. Analogue Model Conforms to IS: 3766-2003, IS: 1598-1977, IS: 1757-1999, IS: 1499-2003 & BS: 131 Part, II, III, IV.
- Digital Model Conforms to IS, BS Standards as above & also conforms to BS EN:10045-1993 (for Charpy)
- Works on pendulum principle, difference between height of drop of pendulum before rupture and height of rise after rupture of specimen is directly proportional to impact energy absorbed.
- Direct indication of impact energy absorbed by specimen on large dial for Analogue model and digital display for Digital model .
- Safety guard for operator.
