Ultra-Large Single Test Space with Adjustable Crosshead - The KPX features an ultra-large single test space with adjustable crosshead options that allow the working space to be configured for a wide range of specimen sizes, test fixtures, and accessories — providing exceptional versatility across tension, compression, and bend applications.

Linear Guidance System - A precision linear guidance system maintains accurate alignment of the load string throughout the full stroke of the actuator — ensuring consistent, repeatable results even under high-force conditions where alignment is critical to measurement accuracy.

Co-Axially Mounted Encoder - The co-axially mounted encoder measures actuator travel directly at the center of the load string, providing accurate displacement data unaffected by mechanical play or offset measurement errors.

Long Stroke, High-Speed Actuator - The long stroke, high-speed actuator accommodates both tension and compression testing applications and provides the travel range needed for large specimens and fixtures, including rebar bend testing and extended elongation applications.

Ergonomic Handset - An ergonomic handset with a fine position adjustment wheel, two programmable softkeys, and start, stop, return, and variable speed jog functions keeps system controls accessible at the test frame — improving operator comfort and productivity during specimen setup and testing.

Bluehill® Universal Software - Powered by Bluehill® Universal, the KPX delivers powerful yet user-friendly test setup, data acquisition, and reporting. Pre-loaded templates for commonly used ASTM, ISO, and EN standards simplify method setup, while Instron Connect remote support is built directly into the software for fast, efficient technical assistance.
