Should I rent one multi-parameter IAQ meter or separate instruments?
A multi-parameter meter is the right choice for most building investigations and comfort surveys—it gives you CO₂, temperature, humidity, and sometimes CO or VOCs in one device. Separate instruments make more sense when you need best-in-class performance for a specific parameter (e.g., compliance-grade CO measurement, calibrated particle counting) or when you're monitoring multiple locations simultaneously.
Which IAQ monitor should I rent: Q-Trak XP, EVM-7, or Aethair PRO?
Rent the Q-Trak XP when the customer wants a current-generation multi-parameter IAQ platform for common building investigations. Rent the EVM-7 when the job benefits from a broader environmental meter workflow and the available sensor package fits the project. Rent the Aethair PRO when the customer mainly needs a simple, portable IAQ screen and does not need the same workflow depth as the TSI platforms.
What should I measure first for most indoor air complaints?
Start with CO₂, temperature, relative humidity, and PM2.5. Add VOC screening when odors, new materials, cleaning products, or chemical sources may be contributing to the complaint.
What's included with an indoor air quality (IAQ) monitor rental?
Most IAQ monitor rentals include the instrument with sensors for CO₂, temperature, and relative humidity at minimum. Many also include CO and total VOC sensors. Calibration certificates are typically included. Accessories like data cables, software, or wall mounts may be available—confirm what's in the kit before your rental ships so you have everything you need on-site.
Where should I place an IAQ monitor?
Place it in the occupied breathing zone, away from supply vents, doors, windows, and direct sunlight. Keep placement consistent when comparing rooms so the data means something.
What's the first decision in IAQ work: spot checks or data logging?
Start with whether the customer needs a quick survey or a defensible record over time. Spot checks work for fast comparisons between rooms. Logging is the better choice when complaints are intermittent, HVAC cycles matter, or the customer needs report-ready documentation.
What's a common mistake in IAQ reporting?
Taking a few short readings at a convenient time and treating them as representative. If the issue is intermittent, log the conditions and document location, timing, occupancy, and HVAC status so the data is easier to defend.
