AT432D 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, ISO 75, ISO 306. ASTM: ASTM D1525, ASTM D648. GB/T: GB/T 8802. Using industrial computer control, solid-state hard drive, system stability, low failure rate. Digital micrometer measures deformation, real-time curve drawing. The test data can be directly second processing on the PC, test data can be imported into the OFFICE software to edit. Sample racks automatically lift and down, no need manual operation. Easy to operate, precise control. Temperature protective circuit, being independent from the controlling system, is designed to protect the tester when temperature of medium exceeds its using range. Oil tank with pump stirrer and heating pipes or cooling water pipe if optional cooling system is required. Optional cooling system to cool the heating medium from 150℃ to room temperature in about 45min.
