TSI DustTrak II and DRX: Using the Auto Zero Module

This video describes how and why you'd use the DustTrak II or DustTrak DRX with an auto-zero module. The auto-zero module is designed specifically for long-term sampling applications, like 24-hour indoor air quality monitoring or for fugitive emissions monitoring. Includes how to attach and set up the auto zero module for a sampling run. Zero drift can occur if the instrument is run for long periods of time, or from temperature and humidity changes during previous measuring events.
