View Quote

The Q-Trak™ XP Indoor Air Quality Monitor Model 7585 combines multiple gas and particle measurements into a single lightweight, handheld instrument that is easy to use, configure and calibrate in the field.

Designed for IAQ and industrial hygiene professionals, this monitor allows you to add or change gas sensors, so you can expand your indoor air quality assessment capabilities.

Product Details

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.

The Q-Trak™ XP Indoor Air Quality Monitor Model 7585 Kit Includes:

  • Handheld unit with multi-sensor IAQ module (includes sensors for temperature, relative humidity, barometric pressure, particle mass concentration, plus open slots for six different types of gases)
  • CO2 gas sensor
  • Gas calibration cap
  • Carrying case

TrakPro™ Ultra Software

The Q-Trak™ XP Indoor Air Quality Monitor includes the new TrakPro™ Ultra software. From the dashboard of this new software, users can connect directly to the instrument, to download and graph data for analysis.

Data Collection and Reporting

Expanded data logging capacity of the Q-Trak™ XP Indoor Air Quality Monitor coupled with the

included TrakPro™ Data Analysis Software provides the capabilities to work effectively and efficiently as you move from data collection to report generation.

The Q-Trak XP Indoor Air Quality Monitor can store over 100 days of data collected at one-minute log intervals. TrakPro Ultra allows for seamless transfer to your PC, so stored data can be recalled, reviewed on screen, and downloaded for data analysis, graphing and exporting for building reports. This software is useful for analyzing long term, unattended data logging studies common in IAQ investigations.

Wi-Fi wireless connection connects the TrakPro Ultra software on your PC directly to the Q-Trak XP Indoor Air Quality Monitor or via a local network to capture and download data remotely.

Gas Sensor Options

The Q-Trak™ XP Indoor Air Quality Monitor Model 7585 can be configured to monitor a variety of gases. A total of 6 sensors can be installed and used at one time, with the ability to mix-and-match. Please note, the Model 7585 kit includes one carbon dioxide sensor.

All sensors are pre-calibrated and include a certificate of calibration.
