Scratch resistance testing device PSHT series

hardnessautomaticmanual

PSHT-40 Scratch Hardness Tester is a unique test instrument to determine the resistance to scratch under a specified load. Tests are conducted either on a go/no go basic by testing at a single specified load on the Diamond Stylus tip or by increasing loads to determine the minimum load at which the coating is penetrated. PRESTO Scratch Hardness Tester is designed as per standard ASTM G171-03. Features: • Hand operated oscillating arm with Teflon rollers for noise free movement • Highly accurate test results under uniform load and specified diameter. • Equipped with Teflon rollers to minimize friction • Uniform load by weights on Diamond Stylus tip for evenness in testing • Firm holding of Test sample by Steel Clamping pins • Cam system for oscillating arm movement • Instant braking system • Light Indicator for sample failure notification PSHT-80 Scratch Hardness Tester Motorised is a unique test instrument to determine the resistance to scratch under a specified load. Tests are conducted either on a go/no go basic by testing at a single specified load on the diamond stylus tip or by increasing loads to determine the minimum load at which the coating is penetrated. PRESTO Scratch Hardness Tester is designed as per standard ASTM G171-03. Features:- • Motorised oscillating arm with Teflon rollers for noise free movement • Ergonomic design with Electronic controls • Highly accurate test results under uniform load and specified diameter. • Equipped with Teflon rollers to minimize friction • Fully Automatic testing through motorised system • Uniform load by weights on Diamond Stylus tip for evenness in testing
