XRW-300B Thermal Deformation and Vicat Softening Point Temperature Measuring Instrument
Product introduction;
Thermal Deformation and Vicat Softening Point Temperature Tester is mainly used to measure the thermal deformation of non-metallic materials (such as plastics, rubber, nylon, electrical insulating materials, etc.) and Vicat Softening Point Temperature.

The 10-dimensional card load bar is equipped with a load plate, fixed on a rigid metal frame, and can move freely in the vertical direction. The load bar and the metal frame components shall have the same expansion coefficient.
The 11 pressure needle is a cylinder made of hard steel, 3 mm long and 1.000 (+0.015 mm 2) cross-sectional area. The lower surface of the pressure needle should be flat, perpendicular to the axis of the load rod and without burrs.
The shape size of 12 is 645 mm x 670 mm x 1450 mm.
Functions implemented:
1. Real-time display of test temperature and temperature-deformation curve.
2. During the test process, the load mass required for the test can be calculated automatically by inputting the size of the sample.
3. Up-line temperature and deformation are set arbitrarily in the range of use.
4. Errors are automatically corrected by software.
5. The color of the test curve can be set arbitrarily, and it can be displayed and hidden in real time, and the width of the curve can be changed arbitrarily.
6. When the test is completed or the upper limit temperature is reached, it has the alarm function and stops heating automatically.
7. Print the test curve and report after the test is completed. The historical records of previous tests are inquired, and the test curves of previous tests can be redrawn.
