Presto's Glass & Plastic Polariscope - Strain Viewer stands out as the premier and highly efficient testing device for measuring residual stresses and strains introduced during the manufacturing process of transparent glass or plastic products, profoundly impacting product strength.
Utilizing the photoelastic technique, it harnesses the power of polarized light passing through the product, enabling qualitative or quantitative interpretation of the resulting optical interference pattern. For glass products, it primarily measures residual stresses, whereas for plastic molding, casting, or extrusions, it focuses on strains. The instrument is meticulously manufactured, adhering to relevant parameters and standards set forth by esteemed regulatory bodies.
User-Friendly Operation: The testing machine is designed for easy and intuitive operation, ensuring hassle-free usage.
Highly Reliable Monochromatic Light Source: Equipped with a dependable monochromatic light source, providing optimal visualization for accurate testing.
Exceptionally Accurate Results: The testing device delivers highly precise and reliable test results, ensuring confidence in the data obtained.
Comprehensive Documentation: Supplied with an instruction guide and calibration certificate, endorsed by NABL approved Labs, ensuring transparency and compliance with standards.
The Presto Melt Flow Index Tester is your go-to solution to evaluate the flow properties of molten plastics or resins. This tester is designed to measure the Melt Flow Index of thermoplastic materials and, hence, determines the rate of flow in grams per ten minutes of molten resins through a specific jet length and diameter.
