Automatic Thermal Deformation Vicat Softening Point Tester

This machine is a non-metallic material testing instrument designed and manufactured according to the latest international standards and national standards. It is mainly used for non-metal such as plastic, hard rubber, nylon, electrical insulating materials, long fiber reinforced composite materials, high strength thermosetting laminates. Determination of the heat distortion temperature of the material and the Vicat softening point temperature. 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. It adopts single-chip control, PID phase-modulated output, with upper limit temperature setting, and automatically stops heating when the test temperature reaches the upper limit temperature..

Features

Intelligent PID adjustment, accurate heating rate, precise temperature control, and no difference.

The softening point test machine can do thermal deformation tests of various standard splines.

It can do the Vicat softening point tests of various standard splines.

Simultaneous thermal deformation and Vicat softening point test.

The required load can be automatically calculated according to the test standard and spline size.

Choose two heating rates, switch freely, and make them easy to operate.

Support multi-stripe test. Color separation processing of the test curve intuitively sees the test process of each group of samples.

The test is completed, or the upper-temperature limit is exceeded. And the temperature control is automatically turned off and shut down.

Double protection of software over-temperature protection and external mechanical over-temperature protection so that the test has no worries.

Diversified report settings, perfect report printing function.
