 Specification
  • No.121 BRITTLENESS TEMPERATURE TESTER
    • This tester is used to measure the 50% impact brittleness temperature of plastic, rubber, and electric insulated wire at low temperatures. By attaching  one end of the test specimen  to the holder and impacting the other end, the operator is to check for any damage to the test specimen. The 50% impact brittleness temperature  is calculated from the amount  of damaged  samples. The refrigerating  method is dry ice for this model.
  • No.121-R BRITTLENESS TEMPERATURE TESTER (WITH REFRIGERATING MACHINE)
    • This tester is used to measure the 50% impact brittleness temperature of plastic, rubber, and electric  insulated  wire at low temperature. By attaching one end of the test specimen to the holder and impacting the other end, the operator is to check for any breaks to the test specimen. This model type is equipped  with a refrigerator.
  • No.121-RA BRITTLENESS TEMPERATURE TESTER (WITH REFRIGERATING MACHINE/ ROTARY HOLDER TYPE)
    • This tester is equipped with a rotary holder to continuously run a maximum of 4 tests. The test conditions (test temperature and dip time) for each of the 4 tests can be set via touch panel screen, enabling continuous efficient testing.
  • No.121-AUTO  BRITTLENESS TEMPERATURE TESTER (FULLY AUTOMATIC)
    • This tester is the fully automatic version of the BRITTLENESS TEMPERATURE TESTER. By inputting the test conditions via computer software, the operator can continuously run 40 tests (200 samples) in a row.
