TSI Q-Trak 7575 Indoor Air Quality Monitor

CO₂, CO, temperature, & humidity

The TSI Q-Trak 7575 is a portable air quality monitor that records multiple indoor parameters in a single device. It measures carbon dioxide, carbon monoxide, temperature, and humidity, and also calculates values such as dew point, wet bulb temperature, and outside air percentage. The unit works with a range of plug-in probes, including options for VOC detection and airflow measurement, and can log up to 39 days of readings for later review. Data is managed through included TrakPro software, with models available in standard or bluetooth configurations for flexible transfer and reporting.
