Q&A Why is the company’s product quality trusted overseas?
Q1: What are Nanjing Qiyuan’s main products, and how does its factory support supply?
Nanjing Qiyuan mainly sells sensors (e.g., temperature, pressure ones), transmitters and controllers, mostly for overseas markets. Its factory in Huai’an Industrial Development Zone, Jiangsu, is key to supply. It has advanced assembly lines and a dust-free workshop for sensor calibration, enabling stable monthly output over 25,000 units to meet overseas demand.
Q2: Why is the company’s product quality trusted overseas?
Quality is its advantage, with the factory ensuring this. It follows ISO 9001 standards: raw materials are strictly checked, and key steps use automated testing. All products, like transmitters, undergo 48-hour stability tests in the factory’s chambers. This makes over 99% of products meet global standards, winning trust abroad.
