The low-power NDIR sensor developed by Shanghai Intersense is oriented at the whole world. By benchmarking with the world's leading brands, Intersense adopts the LED low-power design to meet the safety certification requirements of Europe, the United States and China, and it has successfully obtained ATEX and IECEx international safety certificates. This sensor has become the first NDIR product of China to obtain this international certificate, and it has successfully substituted the imported products with its good performance. Shanghai Intersense has an excellent R&D team which has gathered technical talents with rich experience in the design, production and application of gas sensors; those relevant R&D engineers have worked in the area of gas detection for more than 10 years and have accumulated abundant practical experience. This infrared NDIR gas sensor can avoid the risks which come with the design of the existing instrument products to the largest extent, and can be widely used in various detection scenarios, being a kind of cost-effective infrared NDIR sensor.
