1、 Product Introduction

Shandong Yuntang Intelligent Technology Co., Ltd., as a professional enterprise engaged in research and development, production, and sales of micro meteorological instruments, has been committed to promoting the application of micro meteorological instruments and meteorological environment solutions. With a complete production chain, strong technical team, and comprehensive marketing team, we have developed and produced meteorological products such as ultrasonic anemometers, five element micro meteorological instruments, six element micro meteorological instruments, and small automatic meteorological stations. These products have been widely used in meteorological monitoring, urban environmental monitoring, wind power generation, navigation ships, airports, bridges, tunnels, and other fields. Our customers are spread all over the country and have achieved good social and economic benefits.

Compared with traditional micro meteorological instruments, our products overcome the need for high-precision timers and avoid measurement inaccuracies caused by sensor startup delays, demodulation circuit delays, and temperature changes.

The YT-WQX12 twelve element micro meteorological instrument, also known as the atmospheric pollution environmental monitoring instrument, is a highly integrated instrument developed by Shandong Fengtu IoT Technology Co., Ltd. to monitor six pollutant parameters including PM2.5, PM10, CO, SO2, NO2, O3, as well as 12 parameters including air temperature, air humidity, wind speed, wind direction, atmospheric pressure, and optical rainfall, in response to the increasingly severe environmental protection situation. The main function is to conduct 24-hour continuous online monitoring of conventional pollution factors and meteorological auxiliary parameters in the air, provide the analyzed data to the environmental protection bureau as a reference for air quality, and assist in environmental decision-making. In addition, optional options include hydrogen sulfide, volatile organic pollutants, sunlight radiation, noise, etc.

The YT-WQX12 air pollution environmental monitoring instrument can be applied to urban grid environmental monitoring and control, smart street lights, scenic area environmental monitoring, factories or mines, construction sites (dust monitoring), urban roads, highways, public places and other places related to air quality monitoring.
