Air Quality Sensors

Whether they're used in industrial or residential settings, air quality sensors reduce the risks posed by pollutants. Along with the ability to trigger household alarms or identify toxic chemicals through carbon monoxide detection technology, air sensors promote safe air quality.

We stock a wide range of air quality sensors to keep homes and industrial systems running smoothly. Our selection includes models from trusted manufacturers like Amphenol Advanced Sensors, Dwyer Instruments, Edwards Signaling, and more. You can use our handy filters to narrow your search by sensor type, output, sensing mode, mounting type, and other features.

What are air sensors?

An air sensor is a type of sensor manufactured to identify and trigger a reaction to physical or chemical properties within the air. It can monitor levels of ventilation, pollution, and other quantifiable matter which could pose a threat to health.

Along with protecting people, however, air quality sensors are frequently applied within industrial machinery and production facilities to ensure that systems operate effectively. From air particle monitors to carbon monoxide and dioxide detectors, air sensors play a fundamental role in hazard prevention.

Which air quality sensors are available?

Carbon dioxide sensors

Carbon dioxide (CO₂) sensors are necessary for a variety of different purposes within industrial settings. In agriculture and research, they can be used to monitor respiration, fermentation, photosynthesis, and other biological, air-producing processes. Additionally, CO₂ sensors play an important role in HVAC systems, alerting operators to any changes in air quality.

We supply carbon dioxide sensors with the following sensing modes:

• Infrared CO₂ detectors
• NDIR CO₂ transmitters
• Optical CO₂ sensors

Smoke detectors

Smoke detectors are the first line of defence against fire. We supply a market-leading range of wall-mounted, infrared smoke detectors suitable for a range of settings. While some models boast a low-profile design to seamlessly blend with their environment, others focus on large-scale operations and can be used within commercial settings.

Particulate matter sensors

An air particle sensor is a device that indicates overall air quality in a certain environment, measured by the concentration of particles. These sensors usually measure the quantity of fine dust particles, quantified in particulate matter.

We supply dust sensors from leading names including Dwyer Instruments to make sure that you only receive products of the highest standard. If you're looking for an air quality device to protect employee lung health, fragile systems, or delicate materials, an air particle monitor ticks the right boxes.

Carbon monoxide sensors

Some of the most critical indoor air quality sensors are those used to detect carbon monoxide. We provide carbon monoxide sensors only from Carlo Gavazzi Inc. and Edwards Signaling. By choosing two brands we know and trust, we can deliver quality, reliable CO sensors.

Carbon monoxide is a deadly chemical by-product of incomplete combustion. In domestic, commercial, and industrial settings, carbon monoxide is produced when fossil fuels don't burn fully. Whether the toxin stems from open fires or leaky gas stoves, having a carbon monoxide sensor in place could potentially save lives.

Humidity and temperature sensors

Our extensive range of air sensors also includes temperature and humidity sensors. These pieces have been optimised to offer advanced capabilities, with selected models able to operate at temperatures as high as 70 degrees Celsius. Paired with their compact size, their durability makes them suitable for a range of industrial and commercial applications.

Where are air quality sensors used?

Safety devices

Air sensors are the trigger for many different types of safety devices, including smoke detectors and carbon monoxide alarms. When concentrations of specific particles are detected, safety devices activate - and often sound an alarm. This alerts people to the immediate danger, helping to prevent catastrophic effects of carbon monoxide, smoke, and other toxic matter.

Electrical appliances

Air sensors can be found in many different household appliances. Refrigerators and air conditioning units, for example, use temperature and humidity sensors - both to display the current temperature and respond to changes in ambient temperature.

In fact, many people now opt to install an air quality monitor in their home, since poor air quality is still a major health implication in the USA and across the globe. These compact devices rely on the type of internal air sensors that we supply.

Pollutant detection

In the current climate crisis, air pollution sensors play an integral role in protecting people living in cities across the world. Without an accurate and reliable air pollution detector, local and national authorities would be unable to take necessary steps towards cleaner, safer air.

Research and education

CO₂ detection is an important part of indoor and outdoor research activities. Scientists use air particle monitors to measure and improve their understanding of specific pollutants, particularly in studies relating to climate change. In educational settings, portable carbon dioxide meters and other devices use air-sensing technology.
