Air Quality Meters

Air quality meters are devices designed to monitor and check the quality of the indoor and outdoor air. These compact, handheld machines are able to measure all essential parameters such as humidity, temperature, air volume, air velocity, CO, CO2, and % of outdoor air calculation.
These devices are ideal for detecting indoor gas leaks and measuring the gas levels such as Volatile Organic Compounds, Formaldehyde, and Freon, Nitrogen Dioxide, Ozone and many more flammable, hazardous or toxic gases.
Some Air Quality Meters store the measurement scores and allow transferring them to the computer for further analysing and reporting.

Types of Air Quality Meters:
- Portable/Handheld Meters – These type of meters are ideal for engineers working on location. They provide accurate measurements and store results for further analysis.
- Desktop/Stationary Meters – Stationery meters are perfect for indoor operation for example in laboratories. They are very accurate in terms of measuring the quality of the air and can be plugged into the main power source so batteries aren’t necessary.

Air Quality meters are necessary devices for every gas engineer and are ideal for proving that gas appliances such as space heaters or kitchen equipment are operating safely.
