Testo 420 Airflow Capture Hood

Description

The Testo 420 Airflow Capture Hood is a lightweight, precise, and convenient volume flow hood used for measuring air flow at larger air inlets and outlets, including swirl outlets. It is designed to ensure compliance with indoor air quality and ventilation guidelines in environments such as hospitals, office buildings, and cleanrooms.

Key Features

• High precision measurement: The Testo 420 includes an integrated flow straightener that calms turbulent airflow often found at swirl outlets. This significantly reduces measurement errors and allows for more accurate volume flow calculations.
• Ergonomic and lightweight design: Weighing less than 2.9 kg (6.4 lbs), the hood is exceptionally light, which is especially helpful when taking frequent measurements or working in high-ceiling areas. Ergonomic handles also assist in comfortable handling.
• Removable measuring instrument: The main instrument can be detached from the hood. When used with optional accessories like a Pitot tube and connection hoses, it can also measure air velocity and volume flow within ducts.
• Tiltable display: The large, backlit 3.5-inch LCD display can be tilted, making it easier to read measurements from different angles.
• App integration: Through Bluetooth, the Testo Smart App can connect to the hood, turning your smartphone or tablet into a second display and remote control. This is particularly useful for taking measurements in hard-to-reach places.
