TestMaster AT3 (tensile) and AT3+ (tensile and/or flex) Automated Testing Systems

The Instron® TestMaster AT3 (tensile) and AT3+ (flex) Automated Testing Systems utilize an innovative design for the automatic tensile and/or flexural testing of plastic specimens. Meeting the testing requirements of ASTM D638 and D790, ISO 527 and 178, as well as other testing standards, this system offers many of the benefits of our robotic AT6 systems, but in a smaller footprint.


AT3 Specimen Holder

More Consistent Testing

The automated specimen loading feature improves repeatability and reproducibility of testing and results, minimizing human influence, and thus, human error.


AT3 TestMaster Full System

Safety & Ergonomics

The AT3 and the AT3+ Automated Testing Systems increase safety by keeping the operator away from the testing area, and improves ergonomics by virtually eliminating repetitive motions associated with high volume manual testing.


AT3 Specimen Measuring Station

30 - 75% of Valuable Operator Time Saved

Free up valuable operator time by automating the specimen measurement and handling portions of the mechanical test. The operator simply loads the tray and lets the system run, uninterrupted. Depending on the materials and the exact tests performed, operators can expect to save up to 75% of their time.
