Product Code : AIT - ASTM
Brand Name : ROCKWELL
Product Description

             FEATURES :

  • For charpy tests on various materials.
  •  Strictly conforms to ASTM-E-2007 specifications.
  • 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 by   specimen and is indicated by a pointer on a large dial for Model : AIT-3000-ASTM & on display for Model: AIT-3000-ASTM(D). 
  • Singal stand design which facilities fast and easy positioning and centering of  specimen which is a basic requirement of sub-zero testing.
  • Unique spring loading braking system for smooth and jerk free braking.
  • NIST approval of machine with samples from NIST-USA, can be arranged.
  •  Model : AIT-300-ASTM(D) is a digital version of Model: AIT-300-ASTM.
