This specialized low-pressure testing system is designed for high-performance quartz inertial devices used in aerospace applications. It enables detection of ultra-low pressure levels down to the mPa range, ensuring sealing integrity and long-term reliability of epoxy resin encapsulated structures. Developed by Baoding Ketu Precision Instrument Manufacturing Co., Ltd., the system meets the stringent testing requirements of space-grade quartz inertial devices. It supports dynamic testing of up to 12 devices simultaneously with an interlocked 12-channel keyboard switch design for efficient operation.
