Q-Trak Indoor Air Quality Meter

Overview

Providing a comfortable, safe and healthy indoor environment is an increasingly important concern. Good air quality increases concentration and productivity. It can also reduce lost days due to absence. TSI's Q-TRAK™ Indoor Air Quality Monitor 7575 provides quick, accurate information to assess key indoor air quality (IAQ) parameters.

On-screen prompts and step-by-step instructions guide the user through operation, instrument setup and field calibration. The Q-Trak IAQ Monitor 7575 also features an ergonomic, over moulded case design with probe holder and a keypad lockout to prevent tampering during unattended use. The Q-Trak IAQ Monitor 7575 is designed to work with a wide range of plug-in probes which expands measurement capability.
