The rugged and durable testo 420 air flow capture hood is an accurate and lightweight air flow instrument.
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 air flow capture hood with ergonomic handles and tiltable display has an exceptional light weight of less than 6.4 lbs. This means that frequent volume flow calculations in large rooms and measurements above head height can be carried out reliably and comfortably. While in use, a large measuring button on the capture hood ensures easy recording of the measurements.
Removable Control Unit
The control unit of the testo 420 enables you to measure flow velocity, volume flow, absolute pressure, temperature, and relative humidity. The automatic zeroing ensures higher accuracy for low pressures. This integrated measuring control unit was not just developed for volume flow measurement at ceiling outlets, as it can be removed from the capture hood and be used for pressure, flow, and volume flow measurements in the duct. You only need to attach a pitot tube and connection hoses (both optional) for measurements in ducts. Timed and multi-point mean calculation, as well as the combination of the two, together with simple input of the duct geometry, provide you with accurate flow measurements in ducts. This means you can save on the purchase of an additional measuring instrument.
Testo 420 App
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.
