The Mullen type Burst Tester evaluates bursting strength of paper, cardboard, corrugated cardboard woven fabrics and rubber-coated fabrics, etc.
M2 (Digital model)
Advanced digital model that supports testing with a variety of highly convenient assist functions.
Stable clamping pressure is applied to sample by compressed air system.
Feeding rate of pressure applying liquid (glycerin) is stable.
Safety mechanism is used in sample clamping unit.
The mechanism is so designed that height of the rubber diaphragm can be adjusted without supplementing glycerin.
When some miss-operation such as operation without a sample occurs, the auto return mechanism operates.
Suitability of expansion under specified pressure of rubber diaphragm can be automatically checked by means of a jig supplied with the machine.
Hard rubber diaphragm can be automatically conditioned or adjusted by means of supplied jig.
Equipped with cross mode to indicate strength of rubber diaphragm at the time of determining true value of bursting strength of sample. (JIS L 1018, L 1096)
Data can be printed out by printer or communicated through RS232C interface. (Option)
