National Standards Compliant HDT VICAT Tester for Deformation Temperature Measurement in Plastics Industry

Equipment introduction​:

• ISO 75-1:1993 "Plastics — Determination of temperature of deflection under load"
• ISO 306:1994 "Plastics — Thermoplastic materials — Determination of Vicat softening temperature (VST)"
• GB/T 1633-2000 "Thermoplastic materials — Determination of Vicat softening temperature (VST)"
• GB/T 1634-2001 "Plastics — Determination of temperature of deflection under load"

Core Technical Features

• PC-Based Control & Data Management: Controlled by a PC, it employs digital micrometers for high-precision deformation measurement, with real-time curve plotting. Test data can be directly processed secondary on the PC and imported into OFFICE software for editing and typesetting, streamlining data analysis workflows.
• Automatic Sample Frame Lifting: Features automated lifting of the sample frame, reducing manual intervention and improving operational efficiency.
• Precision Heating Control: Adopts a constant-speed heating algorithm that integrates real-time and historical temperature data to comprehensively calculate heating control parameters and make real-time adjustments—ensuring exceptional linearity of the heating rate. Essentially, the temperature rise per minute adheres strictly to the standard value. In case of real-time temperature deviations caused by ambient temperature fluctuations or voltage variations, the system automatically adjusts to the standard rate within a short period.
• Safety & Test Termination: Equipped with a temperature alarm function that immediately stops heating control when triggered, ensuring operational safety. It offers three test termination modes: 1) reaching the set displacement; 2) reaching the upper temperature limit; 3) manual termination.
• Enhanced Testing Capabilities: Includes functions such as constant-temperature preheating and expansion coefficient adjustment, which accelerate testing processes and enhance result accuracy. Test results can be saved and printed. Dedicated computer software enables viewing of temperature curves generated during heating and printing of detailed test reports.
• Flexible Workstation Configuration: The instrument comes standard with 3 workstations. Multi-station models can be customized to meet specific user requirements, adapting to high-throughput testing scenarios.
