The Honeywell City Technology industrial gas sensor range is designed to measure a variety of oxygen depletion, toxic and combustible gases, to help keep workers safe in harsh commercial and factory environments. In this article we take a closer look at the features, functionality and applications of each sensor type manufactured by one of the world’s leading names in gas detection. With over 45 years’ experience, the range includes over 300 electrochemical, catalytic bead and optical sensing products detecting 28 common and exotic gases.
Honeywell iSeries digital gas sensors are next-generation ‘plug and play’ intelligent sensors that boast a digital interface and five-year operating life. With numerous built-in smart diagnostics, the iSeries uses intelligent features such as digital traceability and predictive calibration, as well as early warning for sensor malfunction and end of life indication, to decrease downtime and cost of ownership.
Their ease of integration, combined with pre-calibration, drives a significant benefit to OEMs and users in terms of integrating the gas detector sensors easily into instruments.
iSeries multi gas detector sensors target the following gases: Carbon monoxide, hydrogen sulphide, oxygen, sulphur dioxide and combustible gases & vapours. These sensors are often fitted within instruments such as portable life safety devices and hand-held gas detectors.
With an industry warranty of two years from date of dispatch, Honeywell iSeries simplifies instrument design and speeds development.
1 Series
1Series sensors target the following gases: Carbon monoxide, hydrogen sulphide, oxygen, sulphur dioxide and combustible gases.
These gas detector sensors are often fitted within instruments such as portable life safety devices and industrial gas leak detectors. 1Series gas sensors excel in challenging temperature and humidity extremes, such as those found in industrial gas applications.
Engineered with an operating life of five years, Honeywell has designed the sensor platform for the future.
The 3 Series is City Technology's original gas sensor range for oxygen and toxic gases. An industry standard for portable industrial safety gas detection, 3 Series offers a one- to five-year life. A wide variety of sensors are available in this format and can be supplied with 4 mA to 20 mA and mV transmitter boards. The 7 Series is the natural replacement for this first generation range.
High capacity filters and electrodes make the 5 Series suitable for use in emissions applications, along with a fast response and recovery time and durability in harsh environments.
Lower in height than traditional gas sensors, 7 Series is designed for portable and transportable applications across a wide range of gas detection.
Growing global awareness has increased the focus on air quality in regard to current contaminant levels, as well as how to better manage air quality.
These reliable gas sensors detect a variety of gases including carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3) and sulphur dioxide (SO2). They are used mainly for ambient environmental monitoring as they have a high correlation with air monitoring stations and also offer high resolution with a low detection limit.
AQ3 gas sensors are designed for operation in a wide range of environments and harsh conditions. Whilst they are designed to be specific to the gas they are intended to measure, they will still respond to some degree to various other gases, achieving individual compensation for temperature and cross sensitivity.
Available with or without a module board, the AQ3 Series offers high resolution and a low detection limit. The custom-built low noise board achieves high accuracy under ppb level.
AQ7 Series gas sensor are well suited for these environmental applications and detect carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3) and sulphur dioxide (SO2). Honeywell has designed the AQ Series with algorithmic compensation that gives users very high resolution, a low detection limit and long-term stability. Highly accurate, AQ7 has a high correlation with air monitoring stations.

Small in size, CRIR are ideal for normal indoor applications as they are maintenance-free. Offering consistency and repeatability, they easily integrate and deliver enhanced long-term stability. Other features include automatic baseline correction, temperature compensation and UART digital interface.
Potential applications cover HVAC, demand controlled ventilation, indoor air quality (IAQ) measurement, air purification systems and smart /IoT (Internet of Things) systems.
