400563 4200 420 Flow Hood Kit and Meter by Testo
The new testo 420 flow hood system is a lightweight, accurate and convenient solution for balancing volume flow at registers and returns. At turbulent outlets, the patented flow straighteners significantly improve measurement accuracy & stability, save time and eliminate the uncertainty of measuring turbulent outlet ducts. Positioning is especially easy with its ergonomic handles, and low weight of less than 6.4 lbs. The optional tripod stand provides convenient handling when testing in large buildings, or at greater heights. The testo 420 flow hood has a wide variety of optional interchangeable flow skirts in different sizes and configurations. The lightweight testo 420 is easy to setup and disassemble and comes in a convenient rollaround case.
The detachable 420 Multi-function flow instrument provides accurate and convenient measurements using the 420 flow hood, Pitot tubes, or the testo flow matrix. Bluetooth connectivity allows for a wide variety of test functions and reporting options using your smart phone or device. The powerful testo 420 App makes testing and reporting versatile, customizable, and convenient. The detachable 420 Multi-function flow instrument is a powerful and precise differential pressure instrument with available calculating and reporting functions built-in. When installed on the testo 420 flow hood, this multi-function flow instrument can be tilted or positioned for convenient viewing and handling.
View measured data from a remote location wirelessly on a smartphone or tablet (up to 65ft.).
