Description

Dart Impact Tester is a consistent tool for determining the impact of a free falling dart on a plastic film. The energy of the falling dart causes the film to fail under specified conditions. The dart has a hemispherical head and is held by a strong electromagnetic dart holder. PRESTO Dart Impact Tester is manufactured under Test Standard IS 2508:1984(R2003), ASTM D1709-16A. • HMI based Touchscreen Model • Electromagnetic Hold and release mechanism for dart • Sturdy Aluminum Section Profile used • Drop Height adjustable clamp • Automatic Test through Electromagnetic Clamping. • Inbuilt Digital counter for counting number of falls during single test operation • Circular annular pneumatic clamping devices for zero slippage • Single Push operation through Paddle Switch. • Shielding structure to prevent dart from falling out after bounce from sample • Strong base plate with rugged structure • Pass/Fail criteria can be programmed • Method Setting for selecting test methods and performing the test. • Easy Data Management. User can create product identification, user name, dart weight, magnet hold time, percentage failure etc. • Automatic calculations & result through Method Setting as per Standard. • USB option available for storing test data • Data output in data record format. • History Data involves Test method, date, time, Failure mass, strength etc. • Clamping Shield height adjustable collar • Sample holding through Pneumatic clamping. * Air Compressor not part of offer.
