TSI Q-Trak XP 7585 - Indoor Air Quality Monitor
The TSI Q-Trak XP 7585 is a professional-grade indoor air quality monitor that simultaneously measures CO, CO₂, VOC (ppm PID), particulate matter (PM1.0, PM2.5, PM10), particle counts, temperature, relative humidity, and barometric pressure. Its modular design supports up to 6 plug-and-play gas sensors, making it ideal for IAQ assessments, HVAC commissioning, and LEED/WELL certification projects. Optional add-on sensors include TVOC (ppb PID) and Formaldehyde (HCHO), available upon request.

What is the TSI Q-Trak XP 7585 used for?
It's a multiparameter IAQ monitor that simultaneously measures and logs CO, CO₂, VOCs, temperature, RH, barometric pressure, and particulates with real-time graphing. It's designed for IAQ investigations where you need to see how parameters move together — not just one number in isolation.
What are the key measurement ranges?
CO 0–400 ppm, CO₂ 0–5,000 ppm, temperature 0–60°C (±0.5°C), RH 0–100% (±3% RH). VOC, barometric pressure, and PM ranges depend on the specific sensor configuration — confirm at dispatch.
Q-Trak XP vs. a CO2-only meter — when do I need the full suite?
Use a CO₂-only meter when ventilation adequacy is the only question. Use the Q-Trak XP when the complaint or problem could involve particles, VOCs, CO, or a combination — so you can see which parameters correlate with occupant complaints or HVAC events.
Q-Trak XP vs. TSI EVM-7 — which should I choose?
The EVM-7 is built around aerosol mass monitoring with a built-in pump and selectable PM size fractions — best when particulate characterization is the priority. The Q-Trak XP is a modular multiparameter monitor with real-time graphing — best for ventilation and comfort surveys where sensor flexibility matters.
How should I place the Q-Trak XP for reliable results?
Place it at breathing zone height in a representative location — not directly under a supply diffuser, next to an open door, or beside a point source unless that's the exposure scenario. Document placement, HVAC state, and nearby activities so trends are interpretable.
What's a common mistake in IAQ monitoring?
Placing the instrument in a microclimate that isn't representative of the space, then treating the data as building-wide. Always document placement context, and use multiple monitoring locations for large or complex spaces.
What's included in the rental kit?
The Q-Trak XP 7585 monitor, carrying case, USB cable, flash drive with software and manuals, sensor calibration cap, tripod, charger, and screwdriver.
What does it cost to rent the TSI Q-Trak XP 7585?
$225/day and $645/week. Pricing beyond two weeks is by quote. For multi-room IAQ surveys or ongoing building assessments, weekly pricing is almost always more economical. For campaigns requiring simultaneous monitoring in multiple spaces, contact us for a multi-unit quote.
