TSI Q-Trak XP 7585 Indoor Air Quality Monitor

Q-Trak XP™ Indoor Air Quality Monitor can perform a wide range of indoor air quality assessments and data logging. The powerful, compact multi-sensor module supports up to 6 selectable gas sensors while simultaneously measuring particle mass concentration, particle concentration, temperature, relative humidity. Standard IAQ calculations including wet bulb, dew point and percent of outdoor air mix are also supported.

A variety of user selectable gas sensor can be added, changed and calibrated as needed. Housed within the unique modular design, the plug-and-play sensors provide an exceptional level of expansion capacity for responding to the increasing demands of IAQ assessments, while keeping the cost of ownership low.
