MODEL XJJD-50
TOUCH SCREEN DIGITAL DISPLAY SIMPLE BEAM CHARPY IMPACT TESTER
Introduction
This
XJJD-50 digital
impact tester is mainly used for the determination of impact
toughness of non-metallic materials such as hard plastics,
reinforced nylon, glass fiber reinforced plastics, ceramics, cast
stone, electrical insulation materials, etc. It is an ideal testing
equipment for chemical industry, scientific research institutions,
colleges and universities, quality testing and other departments.
Characteristic:
-
This series of
impact testing machine is an intelligent digital display impact
testing machine developed and produced by microcomputer
technology. The advantage is that it can automatically correct
the energy loss caused by friction and wind resistance, and get
rid of the numerical chart of energy correction due to the
influence of resistance. (the detection of the residual energy
of the pendulum and the correction of the energy loss after the
fracture of the sample are completed once in the process of
impact).
-
This series of
impact testing machines use LCD touch screen display to display
the test results, which makes the reading more intuitive and
improves the accuracy and accuracy of the impact machine.
-
The main
technical parameters of
XJJD series
simply supported beam impact testing machine fully conform to
the requirements of ISO 179, GB/T 1043, JB/T 8762 standards.
