In which fields are the products used?

They are used across a wide range of industrial sites including laboratories, factories and plants, hospitals, military facilities, livestock and wastewater treatment, and construction sites for worker safety and environmental monitoring.

Raymond Korea — National Ambient Air Quality Monitoring Network Installation, Community Center Rooftops Nationwide

National Air Quality Monitoring Network — Gas Detector Installation on Community Center Rooftops Nationwide

This case covers a large-scale gas detector installation across the national ambient air monitoring network, located on rooftops of community centers (dong offices) nationwide. This project ranks as approximately the second-largest installation volume in Raymond Korea's company history. When checking real-time fine dust, ozone, and other gas concentrations through public air quality apps and websites, the underlying data originates from exactly this type of monitoring infrastructure — installed on rooftops of community centers across the country.

The Role of Community Center Rooftop Monitoring Stations

Community center (dong office) rooftops across Korea host a distributed network of ambient air quality monitoring instruments
This infrastructure provides the data source for public-facing fine dust, ozone, and air quality information accessible through government apps and websites
Distributed rooftop placement across thousands of community centers provides comprehensive geographic coverage of local air quality conditions
This project represents one of the largest single deployment efforts in Raymond Korea's operational history

Frequently Asked Questions

Where does the real-time air quality data shown in public apps and websites originate?

This data is generated by monitoring instruments installed at distributed locations including community center rooftops nationwide — exactly the type of infrastructure covered in this installation project.

How large was this installation project compared to other Raymond Korea deployments?

This project ranks as approximately the second-largest installation volume in Raymond Korea's company history, reflecting the scale of nationwide ambient air monitoring network coverage.

Why are community center rooftops chosen as monitoring locations?

Community centers provide consistent, accessible, government-controlled locations distributed evenly across population centers nationwide, making them ideal sites for building a comprehensive ambient air quality monitoring network.

What gases are monitored as part of this network?

This installation includes O₂ and H₂ monitoring as part of the broader ambient air quality assessment infrastructure supporting public information systems.
