Luoyang Sigma Instrument Manufacture Co., Ltd

Founded in 1999, Luoyang Sigma Instrument Manufacture Co., Ltd is a high-tech enterprise specialized in R&D and manufacture of all kinds of muffle furnace, industrial furnace, tube furnace, vacuum furnace and high temperature furnace etc. Sigma has the right to the use of 40 acres industrial land and owns 8000 m2 standardized plant and office buildings, 1500m2 administrative and marketing center and 1500m2 ultra-high temperature engineering and technical research and development center. It also possesses four advanced production lines of lab furnace, industrial furnace, ceramic fiber board and furnace chamber, and ultra-high temperature ceramic fiber. In 2006, our company was the first one to develop the ceramic fiber type artificial intelligence box resistance furnace and regarded the over temperature value of 1-3 degrees Celsius as one of the standards to control the temperature in box resistance furnace, the comprehensive performance of which reached the advanced level of the international brand. Sigma, therefore, becomes a well-known brand in laboratory industry. In 2007, our furnace were rated"quality stability and after-sales service satisfied products" by Quality and Technological Supervision of Henan Province. In 2010, our company invented the diorite and zirconium composite ceramic heating elements and thermocouples, the maximum working temperature of which can reach 2600 degrees Celsius. These ultra-high temperature sensors can work under both vacuum and oxidizing atmosphere, marking the history of measuring the maximum temperature in contact-type under oxidizing atmosphere. In 2011, our company set up an Ultra-high Temperature Sintering Experiment and Engineering Center engaged in various sintering experiments at the range of 1000-3000 degrees Celsius, becoming the first high temperature laboratory available to domestic and abroad in China. Up to now we have got 50 technology patents and intellectual properties. As the manufacturer we have passed the ISO 9001:2008 International Quality System Certifications and can provide the OEM/ODE service. Our sigma company with meet the full satisfactory needs of customer as the service concept, has praised by users.
