Non-contact Video Elongation Test Machine Large Deformation Video Extensometer for Rubber and plastic Tensile Strength Testing Machine
1.Introduction
It is widely used in rubber and plastic, polymer materials, adhesives, adhesive tapes and other industries. It is suitable for testing the tensile strength, elongation, elastic modulus, compressive strength, compression rate, etc. of samples under different conditions of room temperature, low temperature and high temperature. It can be switched to use at room temperature, which is convenient and fast, and one machine can be used for multiple purposes.

3. Introduction of extensionometer
The large deformation video extensionmeter is a non-contact, high-precision and real-time large deformation measurement system. It uses an independent digital camera and a real-time image preprocessing algorithm to capture images of the device under test during testing and analyze changes in image features. Real-time dynamic measurement of strain, displacement and other data, suitable for 1000% and above large deformation test. Especially suitable for testing rubber, film and so on. It supports signal communication with the testing machine, and can measure various mechanical performance parameters such as stress-strain curves. It can be used in various large deformation mechanical tests.

4. Features
