TESTRO ELECTRONICS LLC
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.
