Under the circumstances of today's rapid technological development and the fierce competition in the testing meters industry, only a strict quality control system and quality assurance could be the major outstanding qualities in the only-the-best-survive market. We believe long-term quality assurance is therefore one of the key missions of enterprises. Therefore, we set up a quality control center and a system of stringent and effective quality control measures. To strive for transcending excellence, experienced engineers and professional technicians are employed to ensure each piece of raw materials, components and finished products are all tested against AQL standards. Thanks to UNI-T's hard work over the years, its products have reached the international level and have obtained well-known certifications including CE in Europe, UL in the United States, CMC in China and so on.
