Digital penetrometer for direct readout of penetration having Encoder & Decoder arrangement with digital timer 9.9 sec Max. The whole unit is mounted on castor wheels for easy movability.

Impact Testing Machines As per BS, ASTM and ISO Standard for Metal, Nonmetal and plastics range 2.71 Joule to 500 Joule capacity.

Features:

• For charpy tests on various materials.
• Strictly conforms to ASTM-E-23-2007 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-ASTM & on Digital Display for Model- ASTM (D).
• Single stand design which facilitates fast and easy positioning and centering of specimen which is a basic requirement of sub-zero testing.
• Unique spring loaded braking system for smooth and jerk free braking.
• NIST approval of machine with samples from NIST-USA. Can be arranged.
• Digital version of ASTM model will be available soon.

OPTIONAL ACCESSORIES:

• Self centering tong for Charpy test specimen (useful particularl for carrying out tests at sub zero temperature).
• Sub zero temperature bath with digital temperature indicator.
• Go: No-Go gauges for conforming the following parameters of specimen-within the limits specified by the standard.
• Center line of notch from both ends.
• Angle of V notch.
• Depth below standard V notch
• Cross section of 10x10 mm specimen.
• Milling cutter for V notch.
• Charpy & Izod notch (V&U) broaching machines.
• Lateral expansion gauge as per ASTM-E-23.
• Standard impact specimen for verifivcation of machine from NIST-USA (we also undertake calibration of the machine as per ASTM-E-23 including approval from NIST-USA).

Compliance with following International Standards: As per IS: 516, IS: 9399, BS: 1881, ASTM C78 100 kN Capacity flexural machine with Digital Load Indicator cum controller.
