【Operating Instructions】

Designed according to international and national standards, this tester is used to determine the heat softening performance of plastic raw materials or finished products.It features independently developed control software that allows for parameter setting, test control, automatic plotting of temperature curves, saving of test results, and instrument calibration.The instrument adopts a large-span, one-piece specimen rack. The maximum specimen span can reach 100mm. Each support is milled from a single block of steel rather than being拼接 (spliced), ensuring rigidity and consistent thermal expansion, which significantly improves test accuracy. By changing the indenter/head, the instrument can measure both Heat Deflection Temperature (HDT) and Vicat temperature. It uses transformer oil (up to 200℃) or methyl silicone oil (up to 300℃) as the heat transfer medium. A mechanical double stirrer circulates the oil, and the large-capacity tank design ensures stable temperature control and a uniform thermal field.

4. Controlled by a 32-bit ARM embedded system, the instrument offers fast computing and zero instruction delay. It uses a 24-bit AD converter to collect temperature and displacement data, ensuring high accuracy and precision. The LCD interface features a Chinese menu system, making the machine's status and parameters clear at a glance.

• Isothermal Rise Algorithm: The system fuses real-time and historical temperature data to calculate heating control data. This ensures a highly linear heating rate (standard value per minute). If environmental temperature or voltage fluctuations affect the immediate temperature, the system automatically adjusts back to the standard rate within a short time.

5. The instrument features an automatic heating cutoff function when the maximum temperature is exceeded, ensuring high safety.

6. The test stops automatically upon completion, displaying the result temperature for each specimen rack. Results are automatically saved for future reference.

7. This model features a benchtop structure with a standard configuration of 3 stations. Multi-station models can be customized.
