Description
Description:
With the testo 420 volumetric flow measuring bonnet for larger air inlets and outlets, you can quickly and precisely comply with hygienic guidelines and specifications for indoor air quality.
- It provides reliable support when calculating the total volume flow in air handling systems, for example in hospitals, office buildings or commercial buildings
- High measuring accuracy at swirl diffusers thanks to volumetric flow rectifier The volumetric flow is often measured at swirl diffusers
- Due to the swirling air at these diffusers, the air flows are often measured incorrectly
- With the testo 420 volume flow measuring bonnet, these measurement errors can be significantly reduced
- The integrated volume flow rectifier calms the turbulence and changes it into an almost uniform air flow
- It thus precisely calculates the volume flow in the range of 40 - 4,000 m3/h
- Unique lightweight volumetric flow measuring bonnet with quick set-up The volumetric flow measuring bonnet with ergonomic handles and tilting display has a unique weight of less than 2.9 kg
- This makes frequent volumetric flow calculations in large rooms as well as measurements above head height safe and comfortable to perform
- A large measuring button on the volumetric flow measuring bonnet ensures easy recording of the measured values
- The bonnet measures 610 x 610 mm
- We offer additional bonnets as accessories for other ceiling diffusers
- For air inlets and outlets that are particularly high up, the use of our optional tripod is helpful
- It can be pushed up to 3.3 metres
- Setting up the volumetric flow measuring bonnet is quick and easy thanks to the tension rods
- The trolley included in the scope of delivery ensures safe transport
- Create and send protocols directly on site using the app connection Benefit from additional practical functions and download our free app
- With the app connection, mobile devices such as smartphones and tablets can be used as a second display and remote control via Bluetooth
- This is particularly practical when using a tripod with high ceilings
- The app enables live measurement on air handling units using the start and stop function and saving the measurement data in txt format
- You can create the measurement report directly on site with the app
- Measurement results such as the total volume flow and the air exchange rate can be directly assigned to customer-specific report templates
- You can then send your measured values and protocols via the mail function
- This saves you a lot of time and increases efficiency
- Volumetric flow measuring bonnet with removable measuring devicePerformance overview The volumetric flow measuring bonnet for air handling units is equipped with a measuring device for displaying the measured data
- The device can be tilted and removed for convenient reading of the measured values
- With the testo 420 measuring device, you can measure flow velocity; volume flow, absolute pressure, temperature and relative humidity
- At low pressures, the automatic zero adjustment ensures higher accuracy
- All measured values are easy to read on the large, illuminated display
- For analyses and documentation, measurement data can be saved and measurement protocols can be created directly on site on a mobile device via app connection
- The management of the measurement data on the PC is very simple and without additional software via plug & play function
- The testo 420 volumetric flow measuring bonnet with integrated measuring device has not only been developed for volumetric flow measurement on larger ceiling diffusers
- The measuring device can also be removed from the bonnet and used for pressure, flow and volume flow measurements in the duct
- This saves you having to purchase another measuring device
- For measurement in the duct, you only need to connect a pitot tube and connection hoses (both optional)
- Temporal and punctual as well as the combination of temporal and punctual averaging with simple input of the duct geometry support you when measuring in the duct
- Scope of delivery Volume flow measuring bonnet testo 420 including measuring device; 610 x 610 mm measuring bonnet, 5 x tension rods; USB cable, batteries and trolley.
