Vane anemometer with integrated humidity sensor and NTC  thermometer, incl protective cap, batteries and factory calibration record

The Testo 410-2 is designed for the measurement of air flow velocity, temperature and humidity. Testo's own patented humidity sensor guarantees reliable measurement results. Thanks to the integrated measurement with the 1.6 in (40 mm) vane, it is ideally suited for fast spot checks at air vents. A timed mean value calculation is possible. It's very handy, small and easy to operate.

NOTE: The testo 410-1 is a similar product without humidity measurement
