This intelligent testing instrument is used to measure the heat deflection temperature (HDT) and Vicat softening point (VST) of non-metallic materials such as plastics, hard rubber, and nylon. It is ideal for use in universities, research institutions, and quality inspection agencies.
Compliant with the following standards:
GB/T 1633, GB/T 8802, GB/T 1634, ISO 2507, ISO 75, ISO 306, ASTM D1525, ASTM D648
Control Stability:
Highly stable system; supports real-time PC software display of temperature/displacement, curve plotting, data management, and report printing.
Multi-Level Safety:
Mechanical over-temperature protection, software over-temperature protection, auto-stop upon test completion, and admin key access protection.
High Precision:
Grating-type digital micrometer with 0.001 mm resolution; PID temperature control algorithm; Heating rate error ≤ 0.5°C.
