AccuBalance Plus
Air Capture Hoods

Models 8372 and 8373

TSI's AccuBalance Plus Air Capture Hoods measure and data log the air volume flowing through registers, diffusers, and grilles. Weighing just seven and half pounds, the AccuBalance Plus is easy to carry, lift, and use. Simply hold the AccuBalance Plus up to diffuser or grill and read direct airflow of a supply or exhaust on the large digital display. The Model 8373 also accurately measures temperature.

Data Logging Capabilities

Data logging ability allows user to log 1000 data points with a time and date stamp
Flexible configuration of data to match building HVAC system
