GB 1035-1970 Plastic heat resistance (Martin) test method
Microcomputer controlled Martin heat resistance tester
Product model: HMD-300
product description:
The HMD-300 Martin heat resistance tester is designed and manufactured according to the national standards GB1699 and GB1035. It can test the heat resistance temperature of polymer materials such as plastic, nylon, rubber, cable materials and so on.
The Martin heat resistance tester uses an intelligent controller to control the temperature, and the temperature control effect is ideal; the grating high-precision dial indicator is used to make the measured value more stable.
