Established in 2011, Beijing ifanpeng Instrument Co., Ltd. is situated in the Daxing Industrial Development Zone, Beijing, in close proximity to the city's beautiful political and cultural center. Our company boasts a team of skilled and creative professionals, as well as a standardized production team. We have dedicated ourselves to the research and development of industrial instruments, with a particular focus on the field of "wind speed and air volume". Through continuous advancements in hot sphere, hot wire, and hot film principles, as well as our exclusive secondary calibration method, we have achieved a breakthrough in eliminating turbulence jump. Our innovative approach has disrupted the traditional industry practice of using differential pressure to measure air volume. We have also overcome the challenge of accurately measuring micro and small wind speeds, earning a reputation for high precision and stability within the industry. Driven by our core value of "innovation", we have expanded our business to include risk control in the civil industry, utilizing our well-established research and development environment and resources. This has resulted in significant achievements in smart home risk control and catering fume detection. Our Ivan wind speed transmitter is widely utilized in various industries, including power plants, nuclear power stations, wind power stations, chemical plants, HVAC systems, biopharmaceuticals, food cleaning engineering, oil and gas, wastewater treatment, and environmental protection. It is also commonly used in manufacturing industries such as pumps, boilers, compressors, and light industries like complete mechanical equipment, glass houses, and chemical fiber production. In addition, our products are also applied in agriculture, such as vegetable greenhouses, breeding, and cultivation, as well as emerging industries like IOT networks and intelligent homes for complete environmental inspections. Since our establishment, we have remained committed to our values of "innovation, quality, and integrity" in serving both new and existing customers. Our Ivan products have not only gained a significant market share in China, but as a national brand, they have also been exported to countries around the world.
