Testo Australia delivers rugged, lightweight Flow Hood with volume flow hood

Testo has
introduced a new Bluetooth-enabled Flow Hood weighing less than three kilograms
in the Australian market for use by HVAC technicians and other professionals.

The new testo 420 is equipped with a volume flow hood and 16 measurement
points that record differential pressure, temperature, humidity and absolute
pressure readings.

Testo sought to address the need for accurate flow hood readings by HVAC
technicians when developing the testo 420 device. To deliver this specificity,
the company designed the instrument so that it could attach and detach from a
flow straightener, ensuring precise measurements while also enabling professionals
to meet indoor air quality guidelines.

The testo 420 flow hood is engineered for convenience, with the design meeting
the needs of HVAC specialists who often have to register air flow readings at
inconvenient or even hazardous places. Two ergonomic handles have been
integrated to the sides of the testo 420, allowing users to tilt the instrument
to easily read the display.

Another useful feature in the testo 420 enables HVAC technicians to
reach vents in high-ceilinged industrial facilities. Users can attach the
volume flow hood to a tripod and remove the flow hood from the main device. The
tripod is then extended to cover the vent with the technician receiving the
readings remotely.

The Bluetooth-enabled testo 420 also allows easy app integration with
technicians able to quickly download the testo 420 app from Google Play or the
Apple Store, and view real-time measurements on their smartphones.

Key features of testo 420 flow hoods include robust construction to
allow frequent use and withstand rough working conditions; 30 hours of battery
life; ability to operate in temperatures between -5°C and +60°C; 2 gigabytes of
storage; and access to Testo’s cloud allowing the creation of customised report
templates, calculation of total volume flow/air exchange rate, and communication
of measurement values to customers, building managers and other parties via
