Featuring average and real-time testing modes, this accessory head is for use with a modular instrument that measures air velocity and temperature in imperial or metric units. In addition, it estimates CFM, identifies duct obstructions, and rapidly assesses the airflow balance in a conditioned space.
Fieldpiece AAV3 Offers
The model AAV3 accessory head is designed to measure air velocity and air temperature. It can be used to estimate CFM (cubic feet/minute). You can measure air velocity in feet/minute, miles/hour, meters/second, or kilometers/hour. The AAV3 also measures temperature in ºC or ºF.
Features
- Estimate CFM
- Large vane covers most of register’s free area
- Displays average measurement and real-time
- Works with any Fieldpiece expandable instrument or handle or any DMM with mVDC ranges and our detachable leads
- Measures air velocity and measures air temperature
- Measure in hard to reach areas using detachable test leads
- Display readings smoothly in average mode or switch to real-time measurement
- Low battery indicator
- Auto-power off after 10 minutes (may be disabled)
Applications
- HVAC/R system testing
- Air flow measurement
- Temperature measurement
