COMPANY PRODUCT

1. Simple Introduction
It is mainly used for the determination of heat distortion temperature and Vicat softening point temperature of non-metallic materials such as plastic, hard rubber, nylon, electrical insulating materials, long fiber reinforced composite materials, high strength thermosetting laminates. It is easy to operate and precise in control. It is a highly intelligent test instrument widely used in colleges and universities, research institutes and product quality supervision and inspection units.

2. Test Standards compliant
ISO 2507 Thermoplastics pipes and fittings Vicat softening temperature Part 1: General test method
ISO 75 Plastics -Determination of temperature of deflection under load
ISO 306 Plastics.Thermoplastic materials.Determination of Vicat softening temperature (VST)

ASTMD 648 Standard Test Method for Deflection Temperature of Plastics Under Flexural Load in the Edgewise Position

3. Instrument Characteristics
Test stand lifting system
 The automatic lifting function of the test stand greatly facilitates the operation of the test, improves the test efficiency and avoids personal injury.
Advanced control system
With high stability, it is easier to install, test and analyze.
User-friendly software control system
 The imitation digital tube displays the temperature and displacement, and draws the test curve. It provides a variety of coordinate curves for centralized management of the data. It can analyze the test data, print test curves, test data and test reports.
Quadruple security
Multiple hardware and software safety design such as mechanical temperature upper limit protection switch, software temperature upper limit protection, test completion automatic stop and administrator operation key to ensure safe and stable operation of the test.
High precision measurement and control system
The high-performance temperature sensor and the advanced capacitive-type digital display dial gauge are used to accurately measure the small changes of the sample. The advanced PID algorithm and the all-optical isolation phase-modulation module are used for temperature control to ensure that the heating rate error is less than 0.5 °C.
