大型軽量フード付き風量計 testo 420
- Ergonomic: uniquely light at less than 2.9 kg in weight (standard flow hood 610 x 610 mm).
- High-precision: flow straightener significantly reduces the usual measurement errors at swirl outlets.
- Efficient: fast set-up, easy handling and convenient operation via testo 420 App.
With the practical testo 420 App on your smartphone/tablet, you can fully exploit the possibilities of the flow capture hood.
Firstly, this means that you can operate the measuring instrument remotely and secondly, that you can send reports by e-mail directly on site as well.
Overview of the App functions:
- Measuring value monitoring via the testo 420's graphic progression display and remote control
- Creation of reports/documentation with photos or comments and dispatch by e-mail
- Calculation of total volume flow and air exchange rate
- Range of approx. 20 m with no obstructions via Bluetooth Low Energy
- In addition to the very low weight and the flow straightener, the following features will make your day-to-day work easier:
- Ergonomic grips
- Tiltable and removable display
- Funnel-shaped tension rod sockets for quick and easy set-up
- Trolley for secure transport also supplied
- App integration for smartphones and tablets, turning these into a second display and remote control via Bluetooth. Particularly practical for the safe use of a tripod for high ceilings.
Problem for measuring hood volumetric flow at swirl outlets: air turbulence H3>
Solution: volume flow hood from Testo with flow straightener H3>
testo 420 には、フード内部にフローストレーナーがあり、回転式の風の流れを直線の流れに整えます。このことで空調システムの風速を正確に実測することが可能です。
A sound level meter measures the noise level of HVAC systems, amongst other things. Why is this important? With air conditioning and ventilation systems, it is not just a case of these being correctly set in terms of the volume flows and of rooms having adequate fresh air supply or used air extraction. That is merely the obligatory element. The voluntary element: the systems not only have to carry out this task in line with the specifications, but also as quietly and unobtrusively as possible. And this is precisely where the sound level meter comes into its own. It enables you to quickly determine the extent of the noise pollution from a system.
In addition to volume flow measuring hoods, Testo also offers further measuring instruments for air conditioning and ventilation measurements:
Unlike a volume flow measuring hood, this measuring device for volume flow measurement can often be employed as a multi-function instrument. The uses of a multifunctional flow meter therefore include volume flow measurement in ducts/at outlets and determination of comfort level or evaluation of illuminance too.
