Product Description:
The rugged and durable testo 420 air flow capture hood is
an accurate and lightweight air flow instrument.
The hood features a unique flow straightener, which
significantly improves measurement accuracy, saving you valuable time on
difficult tasks
The testo 420 control unit can be tilted for a more
convenient view of the display
The included Bluetooth / app feature allows for wireless
connection to mobile devices, remote monitoring, as well as remote
operation
The testo 420 apps can send measurement reports directly
from the work site via email
For additional convenience, there is an optional tripod
when working with high ceilings, as well as four additional flow hood sizes
available for complete versatility
The testo 420 is also a CEC-approved air flow capture
hood
Live data feed integration is now available with the
MeasureQuick App
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.
Exceptionally Light
The testo 420 air flow capture hood with ergonomic
handles and the tiltable display has an exceptional light weight of fewer 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 the 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.
