Presto designs and manufactures high-quality of Polariscope Strain Viewer for Nigeria, an extremely effective instrument that helps to measure the strain distribution in the quality of the preforms. The instrument helps to view the Preforms under polarized light to detect the defects. The testing instrument work on the principle method that a slight different in the material distribution will change the refractive index of the Preform. Presto offers two model of Polariscope namely – Deluxe model and Computerized model.
Photoelasticity is a most important phenomenon that occurs in Preforms, PET and glass products. It is the process of change in refractive index of the material due to non-uniform distribution throughout the material. This can create a major problem for the manufacturers of glass products as this is a great defect in the quality of the product. This problem can be detected efficiently with the help of Presto’s Polariscope Strain Viewer for Nigeria. The instrument is designed using high-quality material to offer accurate testing procedures and extended service life. The instrument is supplied complete with a user manual and conformance certificate which is traceable to NABL approved labs.
