Polariscope Strain Viewer in Bangladesh

Presto offers superior quality of Polariscope Strain Viewer for Bangladesh, an extremely effective instrument that helps to measure the strain in the quality of the preforms. The testing equipment reflects polarized light on the sample to analyze the defects in the quality of the Preform. The device works on the principle that measures the slight difference in the material distribution with the little variation in the refractive index of the Preform. Presto Stantest manufactures two models of Polariscope for Bangladesh namely – Deluxe and Computerized model.

Photoelasticity is the process that quickly changes the value of refractive index of the material due to uneven distribution of the material. This will generate a major problem for the manufacturers of PET & Preform products and glass products as this is a major flaw in the quality of the PET product. This problem can be solved easily with the help of Presto’s Polariscope Strain Viewer for Bangladesh. The testing machine is designed using high-quality material that offers extended service life to the product and accurate testing procedures. The device is delivered complete with calibration certificate which is traceable to approved laboratories.
