SATRA STM 141F Ross flexing machine

Flexing tests are sometimes required to be carried out at low temperatures. This determines the suitability of materials being tested to flex at temperatures below 0°C. SATRA provides a range of these machines and uses a low temperature cabinet specifically designed to suit the test.

The SATRA low temperature cabinet ensures maximum operator safety by having the electrical control and drive systems outside the freezer area where moisture cannot impair electrical safety. The control system incorporates a digital temperature controller which can be set to achieve the desired temperature from ambient down to -20°C, plus a counter to indicate the number of flexes carried out. The counter can be preset to stop the drive mechanism when completed.

This low temperature version of the Ross flex test is built into a low temperature cabinet. It is used for the flex testing of sole unit samples to assess the effect of flexing under low temperature conditions. It has 12 stations for small samples but can also accommodate larger samples by adjusting the mechanism.
