Since its inception, Laoying Haina Group has taken "For the Well-being of Employees" as its mission. After years of development, the Company has now become a diversified group company integrating environmental monitoring equipment, optical sensing, intelligent data and other industrial fields. The products of environmental monitoring equipment series include smoke and flue gas detector, integrated air monitor, ozone tester, etc. Products of optical sensing platform is based on differential ultraviolet absorption spectroscopy (UV - DOAS), non-dispersed ultraviolet (NDUV) and non-dispersed infrared technology (NDIR) technology. Those products take original designs for multiple reflection and long optical path air chamber and large diameter reflecting telescope. Many gases, including CO, CO2, CH4, SO2, NOx, hydrocarbons, benzene series, alcohol, which have ultraviolet, visible, and infrared optical characteristics with a concentration range covering parts ppb～% level, can be detected by our various optical gas analysis modules. Application scope includes environmental air monitoring, pollution source waste gas monitoring, industrial process gas monitoring, industrial gas leakage monitoring, etc., and we can custom-made a variety of special optical gas analysis modules. The intelligent data platform can provide a variety of products and services such as Internet of Things software, Internet of Things hardware and cloud services according to the needs of the environmental protection industry.
