Air Sensors
Also known as pitot tubes, these can be used with manometers to measure air flow rate. Sensors have inch graduation marks so you can monitor your insertion depth.

Remote-Reading Airflow/Temperature Meters
With a probe on a cord, these meters access hard-to-reach places in duct. They display airflow and temperature simultaneously and can show airflow measurements on multiple scales, such as fpm, mph, and knots.
Use the RS-232 port to transmit data. For a USB connection, you'll need a USB adapter cable (sold separately).
Tube meters have a probe that telescopes to 3 ft. to reach into narrow openings.

Airflow/Temperature Meters
These versatile meters display airflow and one other measurement simultaneously. They’re also known as anemometers or vane meters. They can show airflow measurements on multiple scales, such as fpm, mph, and knots.
Foldable fan meters are small enough to fit in your pocket when closed, then extend to 9” when unfolded.
Meters with a 4” blade diameter give you more accurate readings on large HVAC ducts than meters with smaller blades.

Airflow Meters
Liquid meter is also known as a manometer.
Swinging vane meter is for low-velocity airflow. It is commonly used in spray booths and exhaust hoods.
Airflow Modules for Development Boards
Position these modules in vents or near sensitive electronics to monitor airflow. Unlike handheld meters, these modules continuously monitor airflow and alert you to changes. Connect them to development boards with Qwiic cords or by soldering.
