Using the compressor, this machine can reduce temperature rapidly. The lowest temperature is up to -70℃. 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.
Totally 20 specimens divided into 4 sets can be tested each time. You check the lowest temperature at which the brittle failure occurs after each set of specimens is impacted by the automatic rotation clamp.
