The testo 420 air flow capture hood is ideal for larger air supplies and returns, and enables fast and precise testing and balancing of indoor environmental systems. It provides reliable data with precise calculations of the overall volume flow in HVAC systems.
Volume flow is frequently measured at swirl outlets, and airflow measurements are often incorrectly measured due to the turbulent air from these outlets. Thanks to Testo’s volume flow straightener, you can be confident in receiving high measuring accuracy at swirl outlets. The integrated volume flow straightener calms this turbulence and converts it into a virtually uniform air flow. This enables highly accurate calculations of volume flow in the 24 to 2,354 CFM range.

The testo 420 app enables live measurement streaming of HVAC systems using a smartphone or tablet. The app features a start and stop function and enables you to save your measurement data in .txt format, and creates the measurement protocol directly on site. Measurement results, such as the overall volume flow and the air exchange rate, can be directly assigned to customer-specific folder templates. You can then send your readings and protocols via the in-app email function, saving you a considerable amount of time and increasing efficiency.
