Brittleness Temperature Tester GT-7061-NDA

This machine is designed for determining brittleness of the wire jacket or vulcanized rubber at a low temperature. It is impacted at a linear speed of 2±0.2m/s by a dart after a specimen fixed to the test device is soaked into a medium at low temperature for 5 minutes. The specimen is then checked for cracks, crevices, small holes and fragments at the lowest temperature.

With the two-segment compressor, this machine can　reduce temperature rapidly. The lowest temperature is up to -70 °C (You may add liquid nitrogen to the heat exchanger if you want to test at a temperature lower than -70°C. The　lowest temperature is up to -120°C.).The temperature is highly controllable. The liquid heat transfer medium in the low temperature tank can be stirred by the stirring motor so as to obtain a better uniform temperature.
