The efficient and reliable Illuminator Polariscope is offered by Presto to test the quality and transparency of the various industrial including the PET and Preform bottles. The operating principle of the machine is that any disparity in the refractive index is caused by the different strain distribution, causing the lower transparency of materials. The device is provided in various sizes and specification as required by the customers or clients.
The phenomenon of photoelasticity is a major trouble for the manufacturers which occurs in the PET, Preforms and glass materials. Photoelasticity implies a change in the refractive index of the material caused by uneven distribution of strain throughout the material. This is the major problem for the manufacturers of PET and glass industries and reason of low quality of the Preform.
Presto Illuminator Polariscope is available in Deluxe Model and Computerized Model. For manufacturing the instruments, a high quality of materials are used so that an extended service life and testing procedures are ensured. Presto supplies their instruments by taking caring of all the perspectives, and thus provides the zinc and chrome plating in the instrument for protection against corrosion. The instrument is supplied with the instruction manual and the conformance certificate traceable to NABL approved laboratories.

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.
