Polariscope

Different defects like cracks and strains present in PET & preform products may affect their quality. Testing these defects will help the manufacturers to gain confidence in their product quality. Presto has designed a high-quality lab testing instrument known as Polariscope Strain Viewer-NXG.

Polariscope Strain Viewer computerised is utilized for conducting quality and transparency test. It is used to identify and evaluate residual strain in PET preforms, bottles and similar products.

Presto's Glass & Plastic Polariscope - Strain Viewer is the best and highly effective testing device which is used to measure the residual stresses and strains that are introduced during the manufacturing process of the products that severely affects the strength of the product.

Presto provides the Polariscope, an exceptionally effective strain viewer designed to assist manufacturers in testing the quality and transparency of their products, thereby ensuring the highest standards of quality assurance for customers. The Polariscope operates on the principle that variations in refractive index indicate differing strain distributions, resulting in reduced material transparency.
