1.Introduction to Airflow Instruments Capture Hood Products

Airflow Instruments Capture Hood is ideal for measuring large air inlets and returns, quickly measuring air volume flow and accurately measuring air volumes between 80 and 3,500 m3/h.Airflow Instruments Capture Hood is suitable for fast and accurate measurement of large air inlets/return air outlets, meeting the requirements of the regulations to ensure indoor air quality.Provides reliable support for air-conditioning and HVAC measurements in hospitals, office buildings or commercial buildings.

The built-in airflow rectifier gate allows accurate measurements even in the vortex air outlet.The vortex air outlet requires frequent air volume measurements.Due to the influence of turbulence in the air outlet, wind speed is often not accurately measured.

Airflow Instruments Capture Hood effectively reduces measurement errors.The built-in airflow rectifier gate can effectively reduce eddy current and uniform air flow, thereby achieving accurate measurement of air volume between 80~3,500 m3/h.

Lightweight air volume hood, minimalist setting

The air volume hood is equipped with an ergonomic design handle and an adjustable display screen, and the total weight of the body is only 2.9kg.It means that air volume measurement tasks can be easily and accurately performed even at large conference rooms and above the head height.The protruding measurement button is located on the air volume hood base, ensuring that every reading during the measurement is recorded.

The standard air hood size is 610x610mm.We offer additional dimensions of air volume hood options for more ceiling air outlet measurements.An optional tripod is very helpful for high air inlet and return air vent measurements.The tripod can extend up to 4m long.

The fixed pull rod allows the air volume hood to be assembled quickly and easily.The factory-standard transportation trolley case ensures safe transportation.

Create measurement reports online, use the app to send to the mailbox to download the free app to use more advantages.Through the application and Bluetooth function, smartphones and tablets can be used as second displays and remotely controlled.Especially practical when using a tripod for ceiling height measurements.

When measuring the air conditioner and HVAC system, you can start/end the measurement program through the App and save the measurement results in .txt format.You can create a measurement report online.Measurements, such as total air volume and ventilation rate, are assigned according to the customer's custom template, and measurement results and reports are sent through the mailbox.Helps you save time and improve work efficiency.

2.Airflow Instruments Capture Hood Product Features

The air volume hood suitable for air conditioning and HVAC measurement is equipped with a display screen to display the measurement results.The display can be adjusted to facilitate customers to read measured values from different angles.

Can complete wind speed, air volume, absolute pressure, temperature and relative humidity measurement tasks.The automatic zeroing function ensures accurate measurement under micro pressure.

Backlit display, all measurements can be read in one screen.Through the application, the functions of saving measurement values online and creating measurement reports can be realized, and measured measurement values can be analyzed and managed.Data management can also be performed on the computer without additional operating software.

The air volume hood integrates different measuring instruments and is not limited to the air volume measurement at the ceiling air outlet.Remove the air hood and can also be used for measurement of pressure, wind speed and air volume in the pipeline.Save costs and no need to purchase other instruments.

When measuring the pipeline, just connect the optional pitot tube and connecting hose.Time average/multipoint average calculation function, input pipeline geometry, and use the two to help complete pipeline measurement with half the effort.
