    Product Details

    testo 416 Vane Anemometer

    From Testo, the 416 small vane anemometer with a fixed telescopic probe, designed for measuring the airflow, wind speed and calculating Volumatic flow rate. The 416 digital anemometer provides accurate on the spot readings in small ducts, ventilation grilles and air outlets. Constructed from high-quality impact resistant ABS, the tough anemometer is the ideal instrument for HVAC technicians and service engineers.

    Compact in design, the hand-held instrument uses a high precision mini rotating vane to deliver readings with a high degree of accuracy. With a measuring range of 0.6 to 40 m/s, the Testo 416 anemometer can even be used at low speeds. Featuring a telescopic probe it can easily be extended and used for applications where measuring space is limited or hard to reach.

    An easy to navigate keypad and only 4 control buttons make the 416 meter extremely easy to operate. With minimal effort, the user is able to display air flow measurements directly on the front screen. Accurate volume flow calculation shown in m³/h can also be displayed. Timed and multi-point mean calculation provides additional information on mean volume flow. With a large backlit LCD display all minimum, maximum and flow readings are clearly shown, even in low light conditions. A handy auto-off feature also helps to conserve valuable battery life.
