Features

● 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. (Optional)
