High-precision measurements on swirl diffusers

Air volume flow is often measured on swirl diffusers, which create turbulent airflows that can easily lead to measurement errors. The testo 420 significantly reduces such errors thanks to its integrated flow straightener. This component neutralizes turbulence and converts irregular airflow into an almost laminar stream. Based on these uniform flow measurements, you can accurately calculate the air volume flow within a range of 80 to 3,500 m³/h.

---

Extremely lightweight and quick to assemble

The instrument features ergonomic handles and a display with a large tilt angle, weighing only 2.9 kg. This allows for precise and comfortable regular measurements in large spaces and at greater heights. The large start/stop button on the housing ensures easy recording of measured values.

The standard measuring hood dimensions are 610 x 610 mm. Other hood sizes are available as accessories. The optional tripod (up to 4 m height) greatly simplifies measurements at very high ceiling air outlets.

The device can be quickly assembled thanks to tension rods. The included trolley case ensures safe and convenient transport.

---

Create reports directly on site and send them via the mobile app

Take advantage of additional smart features by downloading the free mobile app. It allows you to connect your mobile device (smartphone or tablet) to the instrument via Bluetooth for use as a second display or for remote control — ideal for measurements on high ceilings using the tripod.

With the mobile app, you can start and stop measurements on HVAC systems, save data in .txt format, and create reports directly on site. Measurement results such as total air volume flow and air exchange rate can be inserted into custom templates. You can then send all data and reports via e-mail, saving time and increasing efficiency.

---

Additional instrument functions

The testo 420 comes with a display for reading measured values, which can be tilted or detached for convenience. It allows measurement of flow velocity, air volume flow, absolute pressure, temperature, and relative humidity. Automatic sensor zeroing ensures high accuracy in the low-pressure range.

All readings are easy to view on the large backlit display. Data can be stored for further analysis or used to generate reports on site using the mobile app. The plug & play function allows quick data transfer to a PC via USB without additional software.

The testo 420 can also be detached from the hood assembly and used for pressure, velocity, and volume flow measurements in ducts. This means you don’t need a separate instrument for these applications. Simply connect a Pitot tube and silicone hoses (available separately). Functions like time and point averaging and simple duct geometry input make the process even easier.

Delivery contents:
testo 420 measuring instrument including housing, 610 x 610 mm hood, 5 tension rods, USB cable, batteries, and trolley case.

testo 440 – Multifunction Measuring Instrument for Air Velocity and Indoor Air Quality Assessment

Use the testo 440 instrument in combination with high-quality probes for measuring air velocity and assessing indoor air quality (probes ordered separately). You can connect up to three probes simultaneously: a Bluetooth® probe, a wired probe, and a temperature probe with a Type K thermocouple connector. Automatic probe detection and clearly structured measurement menus make your daily work much easier.

---

All essential measurements with one device

Perform measurements quickly and easily: the instrument automatically detects the connected probe, eliminating the need to manually configure probe parameters. Clearly structured menus for measuring volumetric flow in ducts/air outlets, funnel measurements, turbulence degree, heating/cooling output, mold risk, and long-term measurements provide all the functionality you need for everyday tasks.

Wireless and compact

The universal handle can be connected to any probe head, allowing you to solve any measurement task while keeping your measurement kit compact and lightweight. The Bluetooth® handle makes your work significantly easier: the wireless connection allows data transmission over a distance of up to 20 meters. If Bluetooth® is not available, you can always use the wired handle.

Practical measurement management

The internal memory can store up to 7,500 measurement protocols, which can be viewed directly on the display or exported via USB to your PC for further analysis. The data is saved in CSV format, which can be opened with Excel, for example. With the optional BLUETOOTH®/IRDA printer, you can also print results directly on site.

Smart calibration concept for maximum accuracy

You can rely on accurate results with digital probes. To prepare for measurement, simply calibrate the probe head and attach it to the universal handle. The instrument can continue operating with other probes during this time.
