ElectroForce 3500 Mechanical Test Instrument

The ElectroForce 3500 test instruments are available in three base system configurations. The 3510 instrument, rated at 7.5 kN, is configured with the linear motor installed in the upper crosshead, making it well-suited for applications requiring a temperature-controlled bath. The 3520 instrument is rated at 7.5 kN, and the linear motor is installed in the lower baseplate. The 3550 instrument is a higher-force configuration rated at 15 kN.
