Indoor Air Quality Meters

Accurate indoor air quality measurements drive better HVAC decisions. IAQ meters in this category give TAB contractors, commissioning providers, and facility teams the data they need to balance systems, verify ventilation, and communicate findings to stakeholders.

What these meters measure:

• CO2 for ventilation adequacy and demand-controlled ventilation tuning
• Temperature, relative humidity, dew point, and wet bulb for thermal comfort diagnostics
• Particulate matter (PM2.5 and PM10) to characterize aerosol loading and filtration effectiveness
• Volatile organic compounds (TVOCs) for source identification and exposure screening
• Differential pressure for room pressurization checks in healthcare and labs
• Air velocity for diffuser performance and localized comfort analysis

Workflow advantages:

• Multi-parameter sensing reduces equipment swaps during walkthroughs and test days
• Data logging and wireless export support trend analysis and defensible reports
• On-screen guidance and clear units help speed up field decisions
• Rugged, portable designs fit tight schedules and busy buildings

Typical applications:

• Ventilation verification aligned with ASHRAE 62.1 and local guidance
• Commissioning and re-commissioning of air-handling and VAV systems
• School ventilation surveys and seasonal readiness checks
• Healthcare pressurization spot checks and room turnover assessments
• Office comfort investigations tied to hot/cold spots or draft complaints
• Filtration performance assessments using PM trends upstream and downstream

Selection tips:

• Choose the sensor set that matches your work: CO2 and RH for ventilation, add PM and VOCs for broader IAQ studies
• Consider logging interval, memory size, and export methods for larger campuses
• Look for calibration access and service options to maintain measurement confidence
• Evaluate accessories such as probes for velocity or pressure to widen capability

Reporting and communication:

• Standardized templates and logged datasets help compare pre- and post-adjustment results
• Trend charts can highlight ventilation shortfalls, filter load changes, and seasonal impacts
• Clear visuals help explain findings to school leaders, healthcare teams, and building owners

Best practices:

• Stabilize the instrument at ambient conditions before high-impact measurements
• Capture readings at occupant breathing height for comfort and CO2 surveys
• Use time-weighted averages where appropriate to reduce noise in variable spaces
• Pair IAQ meters with capture hoods and anemometers for a full ventilation picture

Service and support:

• Factory calibration and recommended intervals help sustain measurement quality
• Training resources and application notes support consistent field methods
• Integration with balancing software can streamline documentation and handoff

By combining the right parameters, reliable sensors, and efficient data workflows, these IAQ meters help teams quantify conditions, prioritize adjustments, and demonstrate results across schools, hospitals, labs, and commercial buildings — supporting healthier, more comfortable, and energy-aware operation without slowing down TAB schedules.
