PET and preform products are widely used in different industries to pack and store different items accurately. These products offer a number of benefits that make them ideal for a wide range of applications. They are lightweight, strong, and durable, making them perfect for use in a variety of industries. But, do you know, even a small defect present in these products may affect the product quality? Thus, to overcome this problem, we at Presto has designed one of the high-quality lab testing instrument known as Polariscope Strain Viewer – NXG. This newly launched laboratory testing equipment will accurately test the defects present in the products including cracks, stress, and strains.

This quality lab testing equipment provides a sharper and clearer optical viewing experience that will help the manufacturers to detect the presence of defects in this testing equipment. In this blog, we are going to discuss brief information about the use of the Presto Polariscope Strain Viewer-NXG model and how this quality testing equipment is helpful in detecting the defects present in the products. But first, let us discuss the need of testing PET & preforms against stress and strains.

Need of testing PET & Preform products against stress and strains

As we have discussed above, PET products are widely used in a variety of industries to store and deliver products accurately. However, before PET can be used in different applications, it must undergo extensive testing to ensure that it can withstand the stresses and strains of use.

To ensure that quality products will be delivered to the customers, we at Presto have designed a high-quality lab testing instrument known as the Polariscope strain viewer that plays an efficient role in determining the polariscope for glass of products by detecting the stress and strains present in them.

This testing equipment has been designed with high-end features that make it easy for the manufacturers to test the defects present in preforms easily.

The Polariscope strain viewer designed by the experts at Presto will work on the principle that any change in refractive index is due to different strain distribution and this leads to lower transparency of the material. Now, let us discuss brief information about Presto’s newly launched Polariscope NXG model and how this quality testing equipment will ease the process of detecting stress and strains present in the products.

All about Presto Polariscope strain viewer NXG model

Testing PET products against stress and strains are essential to ensuring that they will perform as intended in their end-use applications. To ensure that these products will be free of any defects, one can easily make the use of a Presto Polariscope strain viewer.

We have recently launched the Polariscope strain viewer NXG model that will help to test the quality and transparency of the products and detect the defects present in them. The products can be visualized for defects at 45 degrees and 90 degrees of angles. The best part is that the measuring angle will automatically detect the angles and provides a clearer and sharper optical viewing experience.

Two light intensities will be offered by this quality testing equipment that includes monochromatic light and sodium lamp. It has been equipped with highly advanced features that we have mentioned below.
