Introduction

JBS series digital display  Semi-Automatic Charpy Impact tester is mainly used to determine the anti-impact capability of ferrous metal materials with high toughness, especially for steel and iron and their alloy, under dynamic load. 

This machine can be operated semi-automatically. The pendulum of the machine can be raised or released automatically by button pressed. The equipment is controlled by PLC and indicator by 7 inch touch LCD screen. It has data store and printing function. They are essential testing instruments for quality testing section, university and college, research institution and industrial and mining enterprise. The machine can do the test according to ASTM E23 and ISO 148 or other equal standards.


Features 

► Two Pendulums (big and small) and two scales reading for each testing machine which enlarge the test range of energy.
► Pendulum rising, impact, free releasing is realized as automatically by control remote and LCD controller.
► Safety pin guaranties the impact action.
► Fully PLC control and I/O data processing.
► Test data store and printing function.
► Dial guage and Digital out put synchronous test result.
► Protection shell avoids the hit and break sample splashing.
► Sample and support are easy centering.
► Electromagnetic clutch hold the rasing pendulum. Power sudden off still in safety.
► Easy installation and operation.
