Easy to Use
The Q-TRAK features a menu-driven user interface for easy operation. On-screen prompts and step-by-step instructions guide the user through operation and field calibration. The Q-TRAK also features an ergonomic, overmolded case design and a keypad lockout to prevent tampering during unattended use.

Accurate Results
The Q-TRAK monitor’s state-of-the-art sensors and large, easyto-read graphics allow real-time, simultaneous display of CO2 temperature, relative humidity, and CO.

Data Collection and Reporting
Expanded data logging capacity and the inclusion of TRAKPRO Data Analysis Software provides the capabilities to work more effectively and efficiently. The Q-TRAK can store up to 38.9 days of data collected at one-minute log intervals. The stored data can be recalled, reviewed on screen, and downloaded for easy reporting. TRAKPRO helps you to generate professional graphs for your reports.
