Volume flow hood | testo 420 | The exceptionally lightweight

Sam Hewa — Thu, 07 Oct 2021 03:27:14 +0000

–

The testo 420 volume flow hood facilitates volume flow measurement at larger air intakes and vents thanks to its light weight, accuracy, and convenience. Despite its weight of 2.9 kg, it’s the lightest volume flow hood on the market. This volume flow measuring instrument for swirl outlets sets new standards in measurement precision with the integrated flow straightener. With this, users can easily and accurately comply with hygienic Indoor Air Quality guidelines and volume flow requirements for ventilation and air conditioning systems, such as in industry, offices or cleanrooms.

High measuring accuracy at swirl outlets thanks to volume flow straightener

Volume air flow is frequently measured at swirl outlets. Air flows are often incorrectly measured due to the turbulent air at these outlets.

The Testo 420 enables you to significantly reduce these measurement errors. The integrated volume flow straightener calms the turbulence and converts it into a virtually uniform air flow. This enables accurate calculation of volume flow in the 80 to 3,500 m3/h range.

What the testo 420 volume flow hood has to offer you

Ergonomic — Exceptionally lightweight, weighing less than 2.9 kg (standard flow hood 610 x 610 mm)
High-precision — Flow straightener significantly reduces common measurement errors at swirl outlets
Efficient — Fast set-up, easy handling and convenient operation via the testo Smart App
Compatible – Measurement, documentation and sending of reports in conjunction with the testo 400

Advantages of the testo 420 volume flow hood

Light — Weighs less than 2.9 kg, making it extremely light. This makes a difference especially when you have to take frequent measurements.
Precise — air turbulence at swirl outlets is pacified. This allows reliable measurement of the air flow.
Flexible — optional exchangeable hoods for a variety of measuring tasks.
Efficient — monitor measuring values and send them by e-mail directly on site via App.
Convenient — the tilting display makes it easier to read out the measuring values. By removing the instrument, and with the corresponding accessories, you can comfortably carry out pressure and Pitot tube measurements too.
Smart — the App allows you to use mobile devices as a second display or remote control.
Compatible — Measure and manage measurement and customer data by integrating the testo 400.

Volume flow measurement via App

With the practical testo Smart App on your smartphone/tablet, you can fully exploit the capabilities of the volume flow hood.

For instance, you can then operate the measuring instrument remotely and also manage your measurement and customer data, and as an added bonus, reports can be sent directly on site via e-mail.

Overview of app functions:

Monitoring of readings via graphic progression display and remote control of the testo 420
Creation of reports/documentation with photos or comments and sending them via e-mail
Calculation of total volume flow and air exchange rate
Logging and also storage and management of measurement and customer data with a range of approx. 20 m in free field conditions via Bluetooth Low Energy

With these advantages, you’ll be able to measure volume flow accurately

In addition to its light weight and the flow straightener, the following features will make your everyday work easier:

Ergonomic handles
Tiltable and removable display
Funnel-shaped tension rod sockets for quick, easy set-up
Trolley included for safe transport
App integration for smartphones and tablets. Via Bluetooth, these become a second display and a remote control. Particularly practical for the safe use of a tripod for high ceilings.
Convenient configuration, measurement and documentation as well as simple sending of reports via connection to the testo 400

volume flow measurement at swirl outlets – the background

Problem for measuring hood volumetric flow at swirl outlets: air turbulence

Without an integrated flow straightener, the measurement result can be falsified by air turbulence. Depending on how the flow hits the instrument, the flow velocities measured are either too high or too low.

Solution: volume flow hood from Testo with flow straightener

Flow straighteners pacify the turbulent air so that it hits the measuring instrument in a uniform way and can be reliably measured.

Delivery Scope

testo 420 volume flow hood including measuring instrument, 610 x 610 mm hood, 5 x tension rods, USB cable, batteries, trolley and protocol certificate.
