Laoyinghaina

Qingdao Laoyinghaina Optoelectronics Environmental Protection Group Co., Ltd. After years of development since its inception, it has now become a diversified group company integrating environmental monitoring equipment, ultraviolet and infrared spectrum gas sensors and other industrial fields. In the field of environmental monitoring equipment, there are smoke detectors, comprehensive air monitors, VOC samplers, ozone meters and other products. In the field of optical sensors, there are products based on ultraviolet differential optical absorption spectroscopy (UV-DOAS), non-dispersive ultraviolet (non-dispersive ultraviolet) , NDUV) and non-dispersive infrared (non-dispersive infrared, NDIR) technology, using original design of multiple reflection long optical path gas chambers and large-diameter reflection telescopes, to develop various types of optical gas analysis modules, which can detect CO, CO2, CH4, SO2, NOx, hydrocarbons, benzene series, alcohol and other gases with ultraviolet, visible and infrared optical absorption characteristics, the concentration range covers the ppb~% level, and can realize pumping, diffusion and open light path gases Detection, application scope includes ambient air monitoring, fixed (mobile) pollution source exhaust gas monitoring, industrial process gas monitoring, industrial gas leakage monitoring, medical gas monitoring, etc. Various special optical gas analysis modules can also be customized and developed according to needs.
