Product Description

Testo 420 Volume Flow Hood for larger air inlets and outlets enables fast and precise calculation of the overall air capture on HVAC systems. It helps in frequent air capture calculations in large rooms and measurements above head height can also be carried out reliably and comfortably, thanks to its ergonomic handles and tiltable display which results in a significant loss in the overall weight of the instrument.

The testo 420 measuring instrument enables you to measure flow velocity, air capture, absolute pressure, temperature and relative humidity. The automatic zeroing ensures higher accuracy for low pressures.
All measuring values are easy to read on the large display which has an illumination function. For analyses and documentation, measurement data can be saved and measurement protocols created directly on site using the App connection. Administration of the measurement data is very easy on the PC without any additional software via the plug & play function.
Air Flow Capture Hood with its integrated measuring instrument was not just developed for air capture measurement at larger ceiling outlets. The measuring instrument can also be taken off the hood and used for pressure, flow and air capture measurements in the duct. This means you can save on the purchase of an additional measuring instrument.

You merely have to attach a Pitot tube and connection hoses (both optional) for measurements in ducts. Timed and multi-point mean calculation, as well as the combination of the two, together with simple input of the duct geometry provide you with support for measurements in ducts.
