TF9 Outdoor Air Quality Monitor

Air quality monitoring in harsh environments. The TF9 features high-precision and accurate particle sensing module. Rain & snow-proof, high temperature resistant IP53 protection rating. Provide a variety of communication interface options. Comparison of indoor and outdoor data to develop air quality improvement & energy saving.



Unique self-property particle sensing module adopts the structural design of fully enclosed aluminum casting to ensure structural stability casting to ensure structural stability, air-tightness and shielding, and greatly improve the anti-interference ability.

Specially designed to protect against rain and snow, high and low temperature resistance, UV-resistant and solar radiation hoods.

Temperature and humidity compensation function reduces influence of environmental changes on various measurement coefficients.

Real-time PM2.5/PM10 particles, temperature and humidity, ozone, carbon monoxide, carbon dioxide, TVOC and atmospheric pressure.

RS485, WIFI, RJ45 or 4G communication interfaces. Equipped with an RS485 extension communication interface specially.

Support multiple data platforms and communication protocols, comparison and analysis of the data from multiple observation points in local areas to determine and provide data support for the treatment and improvement of atmospheric air pollution sources.

Communication with MSD indoor air quality monitor and PMD in-duct air quality detector. Allows comparison data of indoor and outdoor air quality in the same area. Provides a verification basis of air quality improvement and energy saving in buildings.

Used for monitoring of atmospheric environment, tunnels, semi-basement and semi-enclosed spaces installed on a column or outdoor wall.
