Shock test systems from CME Technology

CME Technology’s KRD series shock test systems cover the full range of impact and shock testing requirements — from standard pneumatic and hydraulic vertical and horizontal systems to high-energy military-grade and MIL-S-901D compliant naval shock machines. The lineup includes bidirectional systems for large specimens and battery testing, plus pneumatic bump test machines for repetitive impact simulation. Systems support standard shock waveforms including half-sine, sawtooth, and trapezoid where applicable.
