Founded in 2017 and headquartered in Shenzhen, TESTRO Electronics LLC focuses on the secondary sale and flexible rental of high-end electronic test instruments. The team counts 30 employees and operates a 1,500 m² warehouse and inspection center in Qianhai, Shenzhen.
Industry Background & Resource Sourcing
Over the past two decades, rapid advances in China’s radio-frequency sector have shortened production-line refresh cycles to roughly 3–5 years. Leveraging long-term partnerships with equipment OEMs, research institutes, and calibration labs, TESTRO acquires traceable, well-maintained decommissioned or replacement units. Every instrument undergoes a five-step technical check and third-party calibration before entering stock, ensuring reliable performance data.
