Air Quality
The City Technology ranges of Air Quality sensors are available in standard 3 series size versions.
Where a transmitter solution is required, sensors are offered complete with precalibrated 4-20mA transmitters for low and higher measurement ranges. Please download the Sensor Product Listing to view latest options available.
As global leaders in the design and manufacture of gas detection sensors, City Technology is trusted by millions worldwide. City sensors are at the heart of personal and fixed gas detection, monitoring and life saving systems across the globe. Sensor ranges include electrochemical, pellistor (catalytic bead), infrared, PID and MMOS sensors for detecting oxygen, toxic gases, flammable gases and VOCs used in automotive, medical, emissions monitoring, industrial safety and hygiene applications.
Note: Graphics of these sensors are an example only and sensor cap/body colour may vary depending upon gas sensor type ordered or manufacturing modification. Please refer to individual datasheets for detailed information on these sensors and their corresponding dimensions.
