Compression Testers

Instron manufactures a complete range of compression testers for determining the compressive strength of countless materials and meeting the needs of the transportation, construction, and consumer products industries. Compression testing systems utilize varying technologies, such as electromechanical, static hydraulic for high-capacity compression tests, and dynamic with the capability of performing both static and dynamic tests.

(What is a Compression Test?)

Electromechanical compression test systems are crosshead-driven systems characterized by the use of pre-loaded ball screws, guidance columns and digital closed-loop position control. Frame configurations include a single column tester; table or dual column model; and floor models.

High-capacity SATEC™ series systems perform compression tests using static hydraulic technology. This family of universal testers includes some of the most rugged and durable machines ever made. These frames are powered by a hydraulic pumping system that moves a piston assembly to provide the forces necessary for testing.

Dynamic systems are capable of performing both static compression and fatigue tests. The state-of-the-art ElectroPuls™, a new family of lower force electrodynamic test instruments, are all-electric and require no air, hydraulics, water or special utilities.

Specialized Compression Testers

	Concrete Testing: The SATEC RD Series Compression Tester is ideally suited for advanced concrete compression testing where frame stiffness is critical and is available in capacities ranging from 2,000 kN (400,000 lbf) – 5,000 kN (1,100,000 lbf). Common materials tested in compression include concrete cylinders, cubes, masonry blocks and bricks.
	Soils Testing: The DX compression-only testing system can be equipped with automatic exudation detection for soils. Audio prompting and an extended tabletop help make stabilometer testing more efficient and user-friendly for both soils and asphalt testing. Additional features include an upper spherical compression plate with lockout ring eliminating the need for shims.
	Spring Testers: The SF Series spring testers incorporate all the features required to make spring testing easy, accurate, and efficient at a very competitive price. Designed for load testing all types of coil springs, disc springs, wave springs, leaf springs and spring-type components, this cost-effective series is capable of testing springs from 0.5 kN to 100 kN (112 lbf to 22,500 lbf)..
