Testo 420 Flow Hood System

Bluetooth® and free app offers remote monitoring and hands-free operation

This lightweight, rugged flow hood system features Bluetooth® wireless connectivity, a 24” x 24” flow hood with supporting rods, and a manometer with a backlit LCD that can tilt for optimum viewing. The patented flow straighteners within the flow hood provide accurate measurements and saves time at turbulent outlet ducts. Weighing less than 6.4 lbs and featuring ergonomic handles, the hood system offers easy, one-person operation. For increased flexibility, optional flow hood skirts in various sizes and configurations are available.

The manometer provides up to 2 GB of data storage which can be transferred to your PC using the micro-USB cable. The free Testo 420 app allows for hands-free operation and wireless transfer of measured data to your mobile device. Compatible with Apple iOS and Android operating systems, the app lets you finalize and send measurement reports as PDFs or Excel® files via email from the job site.

The detachable manometer can be used as a standalone unit for measuring pressure, airflow volume, and velocity in air conditioning and ventilation ductwork with an optional pitot tube.
