The air quality measuring instruments consists of indoor air quality (IAQ) monitor and outdoor air quality monitor. The main objective to measure air quality is to understand the main air pollutants in our environment, whether is indoor, inside the building, or outdoor, in the open space.

The common IAQ monitor measure pollutants such as dust (PM2.5), carbon dioxide (CO2), formaldehyde (HCHO), and Chemicals (VOCs). There are more outdoor air pollution to monitor, and the top most common types of gases are Sulfur dioxide (SO2), Carbon monoxide (CO), Carbon dioxide (CO2), Nitrogen oxide (NO), Nitrogen dioxide (NO2), Volatile organic compounds (VOCs), Particulate Matter (PM), and Ozone (O3).

In Singapore, visit to view the outdoor air quality information. GMM also provide outdoor real-time dust monitoring system for construction sites, schools, and national parks projects.

The Singapore BCA, NEA & MOH have the Guidance on improving ventilation and indoor air quality in buildings amid the COVID-19 situation. The advisories link as follow:

In 2021, the BCA-HPB Green Mark Healthier Workplaces:2018 and Green Mark:2021 Certification Requirements with 18 points on Indoor Air Quality and 12 points on Spatial Quality. GMM have IAQ monitoring system to meet the criteria.

Wednesday, 4 January 2023 [Singapore] – Minister for Sustainability and the Environment Ms Grace Fu officially launched the “Industry Guidelines for Indoor Air Quality”. The industry guidelines are part of efforts by the Alliance for Action (AfA) on Sustainable Spaces to raise public awareness on the importance of good indoor air quality.

The RESET and WELL Air Standard is a data standard for air quality monitoring used worldwide. REST Air for indoor are quality data is required to be continuously gathered through air quality monitors that measure the five parameters, there are PM2.5, TVOC, CO2, Temperature and Relative Humidity.

GMM Technoworld do sell RESET Air Accredited Monitors for RESET Air projects pursuing Commercial Interior Certification. The list of IAQ monitors: and we have Tonngdy MSD-18, Kaiterra Sensedge, AWAIR Omni, and Kaiterra Sensedge Mini.
