Product Summary
The Comprehensive Materials Testing System includes everything needed to investigate compression and tensile testing, column buckling, three and four-point bending, shear testing, and stress lines with photoelasticity. In addition to everything the Materials Testing Machine provides, the Comprehensive System includes a sturdy, plastic base with convenient storage for all components and accessories.
The Materials Testing Machine measures force with a 7100 N load cell and displacement with an optical encoder. It includes a PASCO Airlink for connecting to a computer through a USB port or Bluetooth, as well as tensile sample sets for testing tension, compression, bending, and photoelasticity.

How It Works
The Materials Testing Machine has a built-in load cell (strain gauge transducer) capable of measuring up to 7100 newtons (N) of force (1600 pounds), and an optical encoder module that measures displacement of the load bar. A crank-and-gear system raises or lowers the load bar on two leadscrews (also known as power screws or translation screws). Force data from the load cell and displacement data from the encoder module can be recorded, displayed, and analyzed by a PASCO Interface with PASCO Data Acquisition Software.
The sensor cable from the Materials Testing Assembly connects to a PASPORT input port and the Comprehensive Materials Testing System includes an AirLink to connect to a USB port on a computer.
The Materials Testing Machine includes a calibration rod and nut, a load bar round nut, and a pair of safety shields with Velcro® hook material.
