High low temperature test chamber for car seat belt
High low temperature test chamber for car seat belt can do high temperature testing , low temperature testing , rapid exchange of high and low temperature testing for car seat belt and other materials.
High temperature testing chamber range ～+175℃,and in the high temperature test, the test temperature can be raised ～+175℃ in just a few minutes,in the low temperature test, the test temperature ~ -50 ℃ only a few minutes.and the key point is that the high and low temperature range can be customized.
Usage:
High low temperature test chambe is application to automotive seat belt metal, plastic, rubber, electronic etc materials and can be used for product improvement’s reference.
Standard:
MTL, IEC, JIS, GJB etc
