Built in airflow rectifier grille, measurable even at vortex outflow vents
Frequent measurement of air volume is required for vortex outflow vents. Due to the influence of turbulence at the air outlet, wind speed often cannot be measured.testo 420Airflow hood
the testo 420Airflow hoodIt can effectively reduce measurement errors. The built-in airflow rectifier grille can effectively reduce eddy currents and achieve uniform airflow, thus enabling measurement of air volume between 80 and 3500m3/h.ultralightAirflow hoodMinimalist settings
Airflow hoodEquipped with an ergonomic design handle and adjustable display screen, the total weight of the body is only 2.9kg. This means that even in large conference rooms and at heights above the head, air volume measurement tasks can be easily performed. The prominent measurement button is located atAirflow hoodBase, ensure to record every reading during the measurement process.The standard size of the hood is 610 x 610 mm. We provide additional sizesAirflow hoodOptional for measuring multiple ceiling air vents. The optional tripod provides great assistance for measuring the intake and return air vents at high altitudes. The tripod can extend up to 4 meters in length.
The fixed rod makesAirflow hoodIt can be quickly and easily assembled. The standard transport suitcase at the factory ensures safe transportation.
Create measurement reports online and send them to email using the app application
Download our free app to access multiple advantageous features. Smart and tablet computers can be used as secondary displays and remotely controlled through the app and Bluetooth function. It is particularly practical when using a tripod for measuring high ceilings.When measuring HVAC systems, the measurement program can be started/ended through the app and the measurement results can be saved in txt format. You can create measurement reports online using the app. The measurement results, such as total air volume and air exchange rate, can be allocated according to the customer's custom template. Measurement results and reports can also be sent via email. Help you save time and improve work efficiency.
replaceableAirflow hood---Advantages Overview
Suitable for HVAC system measurementAirflow hoodEquipped with a display screen for displaying measurement results. Adjustable display screen facilitates customers to read measurement values from different angles.
The testo 420 is capable of measuring wind speed, air volume, pressure, temperature, and relative humidity. The automatic zeroing function ensures measurement under slight pressure.
Backlit display screen, all measurement values can be read in one screen. Through the App application, online saving of measurement values and creation of measurement reports can be achieved, allowing for analysis and management of measurement values. Data management can be performed on a computer without the need for additional operating software.
the testo 420Airflow hoodIntegrating different measuring instruments is not limited to measuring air volume at ceiling vents. Removing the phoenix cover can also be used for measuring pressure, wind speed, and air volume inside the pipeline. This indicates that you are saving costs and do not need to purchase other instruments.
When measuring pipelines, simply connect the optional pitot tube and connecting hose. Time averaging/multi-point averaging calculation function, input pipeline geometry, and combine the two to help complete pipeline measurement.
