The Testo 410 series is a family of compact, handheld vane anemometers designed for quick and accurate air velocity measurements in HVAC, ventilation, and environmental applications. The integrated 1.5-inch vane delivers reliable readings from 0.4 to 20 m/s with accuracy of ±0.2 m/s +2% of reading.

Two models are available to suit different needs: the 410-1 measures air velocity and temperature, while the 410-2 adds relative humidity measurement for comprehensive indoor air quality assessment. All measurements are displayed on a clear, backlit LCD with selectable units. Features include timed mean value calculation for fluctuating flows, Hold function to freeze readings, and Min/Max recording for trend analysis.

The 410 series ships complete with protective cap, wrist strap, belt clip, batteries, and calibration certificate—ready for immediate field use.

Typical applications include:

• HVAC system balancing and troubleshooting
• Ventilation grille and diffuser testing
• Indoor air quality spot checks
• Laboratory and cleanroom airflow verification
