Testo 405i - Hot Wire Anemometer Wireless Smart Probe

Description

The Testo 405i is a wireless hot-wire anemometer that measures air velocity, temperature, and volume flow. As part of the Testo Smart Probes series, it wirelessly transmits measurement data via Bluetooth to the companion Testo Smart App on your smartphone or tablet. This allows HVAC professionals to take measurements in ducts and other difficult-to-access areas.

Key Features

• Wireless connectivity: The Testo 405i connects via Bluetooth to the Testo Smart App on your iOS or Android smart device, providing a remote display for your measurements. This allows you to work without a traditional handheld display, making it easier to take readings in confined spaces.
• Telescopic shaft: The hot-wire sensor is attached to a telescopic shaft that extends up to 400 mm (15.7 inches), making it ideal for in-duct flow measurements.
• Automatic volume flow calculation: Within the app, you can intuitively input the dimensions and geometry of a duct's cross-section, and the app will automatically calculate the volume flow in cubic feet per minute (CFM) or other units.
• Flexible reporting: The Testo Smart App not only displays measurement data as instrument readings, tables, or graphs but also allows you to generate professional reports. These reports can be customized with photos and comments and sent as PDF or Excel files via email.
• Multi-point and timed averaging: For accurate results when traversing a duct, the app can perform a timed or multi-point mean calculation.
• Compact and lightweight: At only 119.6 g, the probe is easy to transport and store.
• Additional applications: When combined with other Testo Smart Probes, such as the Testo 605i thermohygrometer, the 405i can also be used to calculate cooling and heating performance.
