Indoor Air Quality Meters/Monitors

Indoor air quality measurements typically include temperature, humidity, draft, particles (PM2.5) and gases such as CO and CO2. TSI offers several instruments that help you quickly and accurately assess basic IAQ parameters. Maintaining air quality and comfort levels can significantly improve occupant satisfaction (as shown through increased concentration and productivity) and help reduce absenteeism.

 

Health and safety concerns are a growing part of air quality assessment. Energy conservation efforts have made building construction nearly airtight, which, in turn, has made proper ventilation more important than ever.  Gases, vapors and particles can cause adverse reactions in certain individuals, depending on individual sensitivity. Some of these ‘ever-present,’ unwanted contaminants are potentially toxic, infectious, allergenic, irritating or otherwise harmful. Recent studies claim that over one third of the buildings in the United States have air quality problems.

 

It is increasingly important to respond quickly to IAQ complaints and be proactive to identify and resolve potential problems before they get out of control. TSI Indoor Air Quality instruments are designed as high performing instruments to help IAQ professionals identify problems, make corrections and maintain air quality standards in any indoor environment.

The Importance of Diagnostic Tools

Modern buildings are constructed to be airtight for energy efficiency, but this can lead to the buildup of indoor pollutants if ventilation is not managed correctly. Issues like high CO2 levels, erratic temperatures, or the presence of particulate matter can lead to occupant complaints, reduced cognitive function, and increased absenteeism. TSI Indoor Air Quality meters serve as the first line of defense, providing the diagnostic capabilities needed to check the pulse of a building. These handheld instruments allow facility managers and IAQ consultants to spot-check conditions and data log parameters over time to catch intermittent issues.

Comprehensive Parameter Measurement

Our range of IAQ instruments covers the full spectrum of essential measurements.

  • Thermal Comfort: Accurate readings of temperature and relative humidity help ensure HVAC systems are meeting setpoints for occupant comfort.
  • Ventilation Effectiveness: Carbon dioxide (CO2) measurement is a key indicator of ventilation adequacy. Elevated CO2 levels often signal the need to increase outdoor air intake.
  • Pollutant Detection: Specific models include sensors for carbon monoxide (CO), volatile organic compounds (VOCs), and aerodynamic particle sizing to identify sources of contamination.

Data You Can Trust

When responding to an IAQ complaint, the accuracy of your equipment is paramount. TSI instruments are known for their precision and reliability, giving you confidence in your findings. The ability to calculate metrics like dew point, wet bulb temperature, and percentage of outside air simplifies the analysis process. By providing clear, defensible data, TSI meters enable you to make evidence-based decisions to tune building systems. This proactive approach supports a healthier indoor environment, helps mitigate potential health risks, and can lead to improved satisfaction and productivity for everyone inside.
