Testo 405I

Product Highlights

The testo 405i Smart Probe is a wireless instrument for measuring air flow velocity, temperature, and volume flow. It is equipped with a telescopic shaft, which extends to 15” for easy in-duct testing. You can reliably determine timed and multipoint flow traverses.

• Measures air velocity, volume flow, and temperature 
• Measures in-duct air flow, and automatically calculates volume flow (simply enter the duct dimensions) 
• Small diameter (<0.5”) and 15” telescopic shaft length is ideal for in-duct flow averaging and timed traverse 
• Perform air duct leakage tests

Each Unit Includes

• Testo 405i Bluetooth hot-wire anemometer
• 3 AAA batteries
• Certificate of calibration
