Tongdy
High Precision Air Quality Monitor
For Atmospheric Environment and Underground Facilities
(Model No.: TF9-XXXXX-P-Y)

Product Features

This TF9 series of air environmental monitoring instrument is specially designed for atmospheric environmental air quality monitoring, is suitable for severe environment air quality in real-time online monitoring. Its superior performance and quality, has a very high cost performance. With the budget of te air quality monitoring equipment, which is far below themeteorological level, the air quality real-time online monitoring of the air quality of the local area is easily expanded.

Adopt unique proprietary sensing module, fully enclosed casting aluminum structure design, to ensure the stability of the gas closed structure and shielding, greatly improve the anti-interference ability, and module includes a large flow blower oil bearing. Uses the automatic constant flow control technology, has a very high long-term operation stability and longevity. It is specially designed to protect the structure and housing of weather-proof and anti-aging solar radiation shield with a wide range of environmental adaptability.

With the function of temperature and humidity compensation, the influence of temperature and humidity changes on the measurement coefficients is reduced.

Real-time monitoring parameters: fine particulate matter (PM2.5), inhalable particulate matter (PM10), Ozone (O3), carbon monoxide (CO), carbon dioxide (CO2), volatile organic compounds (TVOC), ambient temperature, and ambient humidity.

Provide WIFI, RS485, Modbus, RJ45 Ethernet communication interfaces are optional.

It provides the interchangeable module components specially for regular maintenance, which makes the continuous data complete and reliable, and the regular maintenance is more convenient. Connection data collection and analysis software platform, the realization of multiple local observation point data storage than in data analysis, determine the pollution sources, the environment air pollution source to the atmosphere to provide data support for improving the atmospheric environmental air quality get a lot of analysis data and basis.

• Built-in commercial high precision sensor module, accurate measurement parameters, extremely cost-effective.
• Design of high temperature resistant shell, wider range of temperature and humidity adaptability.
• Suitable for air quality monitoring in harsh environment, which is applicable to the need of the monitoring station of the atmospheric environment to be far away from the actual site.
• Multiple communication interface options, connect monitoring and analysis software platform, to realize data storage, data analysis and comparison.
• Get real-time data and analysis for the vast local area intensive observation points, or as a comparison of indoor data.

With MSD series of indoor air quality monitor, data can be used as indoor and outdoor air quality than the same area, solved due to the atmospheric environmental monitoring sites away from the real environment, so the data error caused by provides improved indoor air quality with the basis of a more effective.

With TFA-18 series air environment monitor, extensible choice: ozone (O3), carbon monoxide (CO), sulfur  dioxide (SO2), nitrogen dioxide (NO2) was applied to atmospheric air environmental monitoring, to form a small air quality monitoring station is applied in more atmosphere or half atmosphere, underground or semi-underground space, and etc.
