From Testo, the 410-1 rotating vane anemometer designed for measuring air velocity and air temperature. The pocket-sized meter provides instant, accurate on the spot readings at ventilation grilles and air outlets. Constructed from high-quality impact resistant materials the robust meter is ideal for HVAC engineers and technicians.

Compact in design, the handheld instrument features an in-built 40mm rotating vane which calculates the wind speed passing through the impeller. With a measuring range of 0.4 to 20 m/s, the 410-1 anemometer can even be used for low flow speeds. In addition, the 410-1 is able to simultaneously measure the air temperature thanks to the NTC sensor.

Operation is simple, just 3 control keys enable the user to easily scroll through and select the desired function. The 410-1 displays the units for air velocity and temperature as m/s, km/h, fpm, mph, kts, Beaufort, ° C, °F and wind chill. With an illuminated display, all recordings are clearly shown on the front screen, even in low light and dark conditions.

Suitable for both indoor and outdoor measurement applications the 410-1 includes a plug on protective cap for extra protection while not in use. An integrated wrist strap also provides extra security.
