Models 8372, 8373
TSI's ACCUBALANCE Plus Air Capture Hoods measure and data log the air volume flowing through registers, diffusers, and grilles. Weighing just three and a half kilograms, the ACCUBALANCE Plus is easy to carry, lift, and use. Simply hold the ACCUBALANCE Plus up to a diffuser or grill and read direct airflow of a supply or exhaust on the large digital display. The Model 8373 also accurately measures temperature.

Features and Benefits
- Balancing mode allows you to easily adjust dampers to a preset value
- Automatic conversion between actual and standard flows (with Model 8372, user initially inputs temperature and barometric pressure)
- Automatic direction indicator displays whether flow is a supply or exhaust (Model 8373 only)
- Variable time constant modes available for a steady display when measuring fluctuating flows
- K factor function enables flexibility for measuring a variety of diffusers
- Variety of hood sizes to choose from, allowing you to take readings from most diffusers, registers, or grilles
- Back-lit display is easy to read in poor lighting conditions
Additional Features
- Optional portable printer to provide hard copy documentation of your measurements
- Compact carrying case for easy transportation
- Field calibration adjustment for convenience
- NIST*-traceable calibration certificate

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
- Automatically sums flows and calculates statistics for branches and systems
- Data can be reviewed on-screen, printed, or downloaded to a computer spreadsheet program
- TSI downloading software permits easy transfer of data to a computer
