Comprehensive Materials Testing System for School, Colleges and Universities Purpose.

The Comprehensive Materials Testing System includes a materials testing machine and a complete range of accessories for investigating compression and tensile testing, column buckling, three-point and four-point bending, shear testing, and stress lines using photoelasticity. It also features a sturdy plastic storage base that provides convenient storage for all components and accessories.

The materials testing machine measures force using a 7100 N load cell and displacement using an optical encoder. It includes a wireless interface for connecting to a computer through USB or Bluetooth, along with test sample sets for tension, compression, bending, and photoelasticity.

Designed and manufactured by Atico Export to meet the practical requirements of modern materials testing laboratories and educational training facilities.

Working principle :

The materials testing machine uses a built-in load cell (strain gauge transducer) to measure forces up to 7100 N (1600 lbs). An optical encoder module measures the displacement of the load bar. A crank-and-
