TES is a professional test instrument manufacturer dedicated to all kinds of hand held equipment. Our goal is to provide top quality products to fit in each customer’s needs. Our company was founded in 1988 with an initial gross investment of 1,000,000 USD and the products line was focused on low cost testers with basic functions. Though we had built up a lot of designing know-how in the first two years in that specific area, we decided to upgrade our product line to high end digital testers. In order to provide the top quality products, the SMT equipments and fully automatic assembly lines were quickly adopted in the company. With determination and efforts, our focus of products line has been gradually shifted to top quality digital testers. Because of the increasing population of personal computer, we had implemented data recording and computer linking capability on several high end products. And we also began to provide environmental monitoring and medical instruments. Now TES has become a corporation with more than 100 employees and with an annual revenue of 10,000,000 USD. We have an excellent R&D team to develop and design new products and customized products according to the required specifications.
