Crystal Instruments Corporation was founded in 1996 by James Zhuge and Justin Tang and operates from Santa Clara, California. The company builds vibration testing, dynamic measurement, and environmental testing kit, with the CoCo-70X vibration analyzer, Spider-80X dynamic signal analyzer, and EDM Modal software among the headline products. Automotive, aerospace, defence, electronics, and medical industries are the principal markets. Precision drives the design ethos - the systems handle modal analysis, predictive maintenance, and MIL-STD testing, and incorporate technologies such as IEEE 1588 time synchronisation (100 ns accuracy) and GPS time stamping. Distribution reaches more than 40 countries, ISO 9001:2015 certification accompanies the work, and the company collaborates with Sentek Dynamics on integrated test solutions. Recent additions include the 2024 Blade Fatigue Testing software module and Signal Viewer for simplified analysis.
