Xifan Electronic Technology (Shanghai) Co., Ltd. was founded in 2006. The company's founder, Xu Wei, has been dedicated to the research and development of industrial sensors for over 40 years. One of his developed products has won the National Science and Technology Progress Second Prize. Due to the perceived gap between domestic and imported sensors, he combined years of sensor research and practical experience to establish this company. We have our own unique product technology and expertise, making us highly competitive in the industry. Whether it's product parameters or lifespan, we are in a leading position among domestic sensors. With strong research and development capabilities, advanced production equipment, and excellent production skills, our company has developed industrial sensors with independent intellectual property rights. We have obtained multiple technology patents and have been honored as a "National High-tech Enterprise." Our industrial online sensors, such as pH electrodes, ORP electrodes, dissolved oxygen electrodes, residual chlorine electrodes, fluoride ion electrodes, and trace oxygen sensors, are widely used in fields such as microbial fermentation, food and beverage, brewing, metallurgy, chemical processes, power plants, slurry, wastewater treatment, desulfurization, pure water, photovoltaic semiconductors, and new energy. They excel in various complex environments, including high temperature, high pressure, high corrosion, strong acids, and alkalis. Our products use internationally universal interfaces, can replace similar foreign products, and can be matched with various specifications of pH transmitters. The quality is approaching or reaching the level of international counterparts, and has received unanimous praise and recognition from users in various industries. We have now established a solid position in the market and our brand recognition is increasing. Xifan Company adheres to the business philosophy of integrity, quality, professionalism, and customer-centricity.
