Liquid Helium Free Physical Property Measurement System

CFMS Series Comprehensive Physical Measurement System: Cryogenic Limited was founded in 1974 in London, UK and has specialized in the development and production of superconducting magnets for over 40 years. The company successfully launched the first commercialized liquid helium-free superconducting magnets in 1992, and has continued to develop liquid helium-free dry superconducting magnet technology for over 30 years. The company is the industry leader in the application of liquid helium-free superconducting technology and has received numerous awards from the European Union and the United Kingdom government. Oriental Chenjing and Cryogenic Limited entered into a partnership in 2000 to provide Chinese researchers with a comprehensive range of physical property measurement systems. After years of cooperation, the two companies have jointly trained an excellent after-sales service team in China, and have set up an after-sales service center in Beijing. We provide a full range of after-sales service to our customers.Cryogenic Limited is the earliest company in the industry to launch a liquid helium-free comprehensive physical property measurement system, and is currently the only company capable of providing a commercialized liquid helium-free comprehensive physical property measurement system with a magnetic field of more than 16 T. The company's comprehensive physical property measurement system is designed to measure the physical properties of the liquid helium in the liquid helium field. Its comprehensive physical properties measurement system is mainly based on the superconducting cryogenic platform (0-18T, 1.6K-400K), combined with magnetic, electrical, thermal, and very low temperature options (Helium III, dilution chiller) and other optional functions of the comprehensive physical properties measurement system.
