Digital HDT Vicat Tester with Touch Screen Controller & Built-in Printer

DESCRIPTION / TECHNICAL SPECIFICATIONS

Introducing an advanced and essential thermal analysis instrument, the automatic HDT & Vicat Tester, designed to provide the most accurate data on the high-temperature performance of non-metallic materials. This device serves a crucial dual function: determining the Heat Distortion Temperature (HDT) and the Vicat Softening Point Temperature. Its applications are extensive, covering tests on plastics, rubber, nylon, and various electrical insulation materials. Most importantly, this instrument fully complies with the requirements of dozens of leading international standards, including ASTM D648 (HDT), ASTM D1525 (Vicat), ISO 75, ISO 306, and DIN, making it a trusted choice for product validation in the global market.

Operated via a modern and intuitive touch screen controller, this instrument is designed for ease of use, stable performance, and unparalleled precision. During the test, operators can monitor the sample's temperature and deformation in real-time, with a clear visualization of the test curve. The exceptional level of precision is reflected in its ±0.5°C temperature control accuracy and an extremely low maximum deformation indication error of just ±0.001mm. The intelligent system automatically stops heating upon test completion, ensuring consistency and repeatability of results while simplifying the laboratory workflow.

The thermal system in this device is engineered for strict standard compliance and efficiency. With a wide temperature control range from ambient up to 300°C, it can test a vast majority of polymer types. Two industry-standard heating rates—120°C/h (2°C/min) and 50°C/h—are selectable to meet specific ASTM or ISO testing protocols. The post-test cooling process is also optimized, utilizing natural or water cooling to efficiently lower the temperature of the heating medium (methyl silicone oil), shortening the turnaround time between tests.

Designed for laboratory productivity, the device is equipped with three experimental racks, allowing for the simultaneous testing of multiple samples. One of its most practical features is the built-in printer. This feature allows operators to print data and test results directly from the machine without needing a connection to a computer or external software. With its combination of high precision, smart automation, and broad standards compliance, this HDT Vicat Tester is a vital instrument for quality inspection units, universities, and manufacturing enterprises to validate and guarantee the thermal properties of their materials.
