Reliable Air Quality Monitor Installations

Air quality monitors use an internal sensor or sensors to detect and track the amount of pollution in the air. This type of monitor can have different types of sensors to detect different types of pollution.

The accuracy and reliability of the sensor are just as important as the better sensor, the more accurate it will be in detecting and report the correct levels of pollution.

There is plenty of variety for air quality monitors available to choose from. Ignite Facilities team of Gas-Safe registered engineers are on hand though, to help you choose the best one for you.

How Air Quality Monitors Work

Air quality monitors can be used indoors and outdoors with either a plug-in or hand-held version available and are mainly used to detect the following –

• Particulate matter (PM)
• Carbon Dioxide (CO2)
• Carbon Monoxide (CO)
• Temperature and humidity levels

Some units detect volatile organic compounds (VOC’s) plus noise levels (dB).

Firstly, we would recommend identifying the right air quality monitor, based upon its intended purpose.
Most air quality monitors available today will be using a form of light scatter to measure PM levels in the air. Light from a source, like a laser, is directed, when it comes into contact with particles in the air and light is scattered, which is then measured to give the PM reading. The rate at which the readings are measured varies, with some sensors able to give readings every few seconds whereas some give readings every couple of minutes or more. More advanced models of air quality monitors also claim to give instant readings with others letting you set the interval of measurements, which can extend the period when the laser needs to be calibrated.

Recent developments of laser sensor technology mean that there is not yet a certified standard for laser sensor to be held in testing. Light scattering sensors are relatively inexpensive, making them a cost-effective choice for any air quality sensors, with the downside being that the readings may not be fully accurate.

Understanding the Results from an Air Quality Monitor

Understanding and interpreting the results from the sensors in your air quality monitor is crucial. Having a good interface, app or website to translate the readings will make them easy to read and understand.

Having warnings such as alerts sent to an app, e-mail or text is a great feature which keeps you fully updated on how polluted the levels are in your environment.
A reliable air quality monitor displays the readings on the unit itself plus it will have the data logging capabilities to track long term patterns. The unit should also be able to discern the cleanliness of air based on a relative measure, meaning it should understand when the air is actually clean, rather than reporting on just changes on the air quality.
For example, if the number of people smoking in a small room drops from 50 to 20 people, some sensors determine that the air is now ‘clean’ because it has improved.
