Metals Impact Tester - Class H 750J - Dual Column Charpy Impact Tester

Impact Energy

300J, 450J, 600J or 750J

Description

The Class H Metals Impact Tester is a dual column impact testing system designed for Charpy Impact testing according to ASTM E23, ASTM E1820, ASTM E2298, ISO 148 and EN10045 industry standards. Class H is designed for high volume and especially hard materials. This unit has the highest accuracy and can be equipped with a force transducer for precise data sampling and complete measurement system. The Class H has a peak capacity of 750J with optional pendulums for 300J, 450J, 600J and 750J. Class Hcomes standard as a fully enclosed system and allows for impact testing at any pre-set angle.This system comes standard with an analog and digital readout for higher accuracy along with the option to add the ability to connectthe system to a computer for use with our analysis software. Class H-4 is an instrumented type meaning there is a force transducer inside the strikerwhich enables the determination of characteristic force, energy and displacement parameters such as pre-maximum force energy (Wm), the post maximum force energy, the general yield force (Fgy), the force at brittle fracture initiation (Fbf) and the arrest force (Fa).

Main Features

  • The heavy cast iron base is mechanically designed to avoid any vibrations having an effect on impact testing results.
  • Dual column impact frame
  • Standard touch screen display and optional connectivity to a PC for software analysis
  • Motor-driven raising of the hammer with auto-return after completion of a test
  • Electromagnet locks the pendulum securely
  • Fully enclosed testing area for the highest safety while undergoing impact testing
  • The pendulum height and weight are precisely designed to ensure high accuracy
  • Simple and easy design to exchange the striking knife to meet ISO or ASTM standards
  • Designed with a high precision bearing for the most accurate impact results
  • Quality PLC controller for precision pendulum testing
  • Optional computer with software control is available for a semi-automatic operation. The operator must only change the specimens while the rest is controlled by the PC.
  • Optional instrumented version with force transducer within the pendulum for detailed software analysis - enables the user to determine the highest amount of data on their specimens
