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.
What our customers say about us is important to us.
Heat Deformation - HDT/VSP Tester is a consistent tool useful for determining the ability of a given polymer to bear load at elevated temperatures. Accurate and reliable deflection or deformation is an important component in the plastics industry.
TP310 is a prominent color measurement instruments used in many mainstream industries which have been designed and manufactured by competent engineers and scientists of Presto Stantest. The instrument has many advantages of other international standard color measurement instruments.
Presto Melt Flow Index Tester is used for evaluating the flow properties of molten plastics or resins. The Melt flow Index of thermoplastic materials is defined as the rate of flow (in grams per ten minutes) of extrudates of molten resins through a jet of a particular length and diameter.
The Presto Melt Flow Index Tester - NXG Model is a reliable instrument used for evaluating and analyzing the flow properties of molten plastics or resins. The determination of the melt flow index of plastic materials is an important parameter in the evaluation of its quality.
