Polariscope Strain Viewer manufactured by Presto is the major testing instrument which is utilized in PET and preform industries to evaluate the defects in the quality of the preforms such as air bubble, water flash marks, crystallization, strain distribution and many more. These defects can make the final product weak and of low-quality standards. To reduce the occurrence of such defects, the preforms are tested prior the production. The testing instrument is equipped with an incident light source and Polaroid lenses. The sample can be tested at two distinct angles of 45° and 90°. The strain viewer can be utilized for testing PET preforms and glasses too. The special model we are offering can be connected to any computer system for defect identification and report generation.
