Anemometer testo 410i vane meter, measuring range 0.4–30 m/s, temperature -20–+60 °C (TESTO 410I)

The testo 410i vane anemometer measures air velocity from 0.4 to 30 m/s and ambient temperature from -20 to +60 °C. It is a compact, smartphone-controlled probe from the testo range intended for HVAC diagnostics, ventilation balancing and quick airflow checks. The probe connects to a compatible smartphone app to display real-time readings, store measurements and perform basic data handling without a separate handheld meter.

Advantages

The compact vane design gives fast, accurate point measurements of air velocity with minimal disturbance to the flow. Smartphone connectivity enables intuitive display, remote use and simple data transfer. The wide velocity range covers low to moderate airspeeds typical in ventilation ducts and outlet grilles, while the integrated temperature sensing provides context for air movement readings. The probe’s robust construction is suited to routine field work and service tasks.

Suitable for

• HVAC system diagnostics and commissioning
• Ventilation balancing and airflow verification
• Point checks at supply and extract grilles, diffusers and duct openings
• Routine maintenance and service inspections

Key specifications

• Air velocity measuring range: 0.4–30 m/s
• Ambient temperature measuring range: -20 to +60 °C
• Vane (rotating impeller) probe geometry for point measurements
• Smartphone app compatibility for display, logging and data export
• Compact, handheld probe format for access to grilles and ducts

How to use

Install the testo smartphone app on a compatible device and pair it with the testo 410i probe according to the app instructions. Position the vane probe in the airflow at the measurement location, ensuring the impeller rotates freely and the probe is aligned with the flow as required for representative readings. Allow the display in the app to stabilise before recording values. Use the app to capture, label and store measurements or export data for reporting.

Usage recommendations

For repeatable results, perform multiple point measurements across the grille or duct cross-section and record the average where necessary. Avoid contact of the impeller with dust or liquids; clean the vane gently when soiled and store the probe in a dry environment. Use the integrated temperature reading to correct or interpret airflow data when environmental conditions differ from standard references.
