HY4320C HDT/Vicat Tester is used to determine the heat distortion temperature (HDT) and Vicat softening point of plastic materials. It is widely suitable for plastic, hard rubber, nylon, electrical insulating materials, long fiber reinforced composite materials, high strength thermosetting lamination materials and other non-metallic materials. This instrument complies with the following international and industry standards. ISO: ISO 2507. ASTM: ASTM D1525. GB/T: GB/T 8802. HY4320C is horizontal type, HY4320D is vertical type. PC control, digital micrometer to determine distortion, real-time display test curve, test software directly process test data, no need to calculate test result by users. Test data can be imported into OFFICE software to edit.
