testo 420 Air Capture Hood (Flow Hood)

The testo 420 accurate, lightweight flow hood with Bluetooth is the precise and convenient solution for measuring volume flows at supplies and returns. Handling this capture hood with flow straightener and tiltable display is especially easy with the low weight of less than 6.2 lbs. and ergonomic handles.

Key Features:

Rugged and toughflow hood that weighs less than 6.2 lbs. (2.9 kg.)
Large, easy to read, tiltable, backlit display (removable) makes it easy to see the readings
Flow straightener for more precise measurement at turbulent outlets
App integration via Bluetooth for fast and easy monitoring and reporting on site

Overview

The rugged and tough testo 420 balometer is an accurate, lightweight flow hood with Bluetooth.

• The capture hood with flow straightener significantly improves measurement accuracy, saving you time and headaches for these difficult situations.

• The display can be tilted for a more comfortable readout.

• Bluetooth allows for connection to mobile devices, which can be used as a second display or remote control

• The App can be utilized to finalize and send measurement reports while still on site

• Use of an optional tripod is especially easy for high ceilings
