Sinowon owns its large factory to manufacture high quality tensile strength machine. Sinowon is mainly engaged in the business of Video Microscope and other product series. A series of tests for Sinowon optical measurement systems is required. The product has been rigorously inspected or tested in the aspects of the electric current, electric field, electromagnetism, input voltage, and surge current. The production is supported by professional engineers. The product features a humanized design. It is equipped with an automatic valve, which means that the filter can be automatically rinsed and back washed according to the running time and the water flow rate. The product is highly praised in many exhibitions such as Shanghai Electronica China Show.
