On May 30, 2025, the State Administration for Market Regulation and the National Standards Administration issued GB/T 45795-2025 "Atmospheric Particles PM10, PM2.5 Mass Concentration Observation Light Scattering Method" . Shandong Nova Technology Co., Ltd. , as a participating unit, relies on its technical accumulation and practical experience in the field of optoelectronic sensing to deeply participate in the standard-setting process and promote the industry to move towards a new era of high-precision and high-reliability monitoring.

This standard is managed by the China Meteorological Administration and under the jurisdiction of the National Technical Committee on Climate and Climate Change (SAC/TC 540) , and the Atmospheric Composition Observation, Forecast and Warning Service Branch of the National Technical Committee on Climate and Climate Change ( SAC/ TC540) . The standard focuses on the core technology of atmospheric particulate matter monitoring, establishes the principle of measuring the mass concentration of atmospheric particulate matter by light scattering method, stipulates the requirements of measuring instruments, measuring environment, instrument installation, operation inspection and maintenance, calibration, etc. , describes the test and measurement methods, and fills the standardization gap in the field of particulate matter monitoring .

Relying on the cutting-edge technology and practical experience accumulated over many years in the field of optoelectronic detection , Nofang has independently developed particulate matter sensors and particulate matter monitoring instruments that are designed and produced based on the calculation methods in this standard , providing a large amount of first-hand data and practical cases for standard formulation, promoting the content of the standard to be more in line with actual needs, and having stronger guidance and operability.

Participating in standard setting requires not only technical accumulation, but also industry representativeness. With 67 invention patents and the first set of taxi navigation equipment in China, NovaSensor has become an irreplaceable "Chinese business card" in the field of particulate matter monitoring.

To promote industry development trends in the global market competition .
