Portable Photoionization Detector (PID)

The VOC-TRAQ total volatile organic compound (TVOC) detector is the easiest way to monitor and record TVOCs using any PC with a Windows® operating system. Using the award winning Baseline®-MOCON® piD-TECH® plus photoionization detector makes the VOC-TRAQ the most reliable, accurate, and inexpensive portable TVOC detector on the market.

Designed for ease of use whether you are an air quality consultant, safety engineer, maintenance manager, or just concerned about TVOCs in your indoor environment.

The USB compatible VOC-TRAQ can operate while connected to a PC, or it can remotely store up to 36,000 sample readings with the detector’s internal memory using the optional rechargeable power supply. Alarm levels are programmable with LED and/or audible notification. The VOC-TRAQ is also compatible with numerous USB accessory options.
