Medical Face Mask Air Exchange Pressure Difference Tester is used to determine the breathability of Protective face masks.The test principle is, measuring the differential pressure required to draw air through a measured surface area at a constant air flow rate, or to test the air exchange pressure of the medical face mask material, which indicates the breath ability of medical face masks.
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.
