Nanjing Luxian Automation Technology Co., Ltd. builds quartz crystal test equipment in Nanjing, Jiangsu. Our machines serve quartz device and crystal oscillator manufacturers.
We hold 34 patents and 15 software copyrights related to quartz crystal testing, and are certified as a High-Tech Enterprise.
We have never tried to widen the catalogue. Frequency testing, sorting and surface analysis — three things, thirty years. Every machine answers the same question: how to measure the frequency at the centre of a die accurately, and have the next person reproduce that result.
From the patented electrode pair on the QB-V-IIID sorter to the micron-level auto-zeroing of the QB-SAT-200, these designs come from problems on the line, not from a brochure.
High-Tech Enterprise certificate, plus the patent portfolio behind the electrode and zeroing designs.


Fifteen quartz device and crystal oscillator manufacturers run Luxian equipment on their lines.
