Testo 417 Vane Anemometer Funnel Set
The measurement of flow velocity and the correct calculation of volumetric flow at ventilation outlets can be a challenge. The turbulence created here and differing flow directions make correct measurement more difficult.
The testo 417 vane anemometer and the testovent 417 measurement funnels provide you with perfect support for flow measurement at ventilation grilles and poppet valves. They ensure simple testing of incoming / outgoing air – such as in the controlled ventilation of living spaces.
The testo 417 vane anemometer with an integrated 100mm vane measures flow velocity, volumetric flow and temperature at the same time. The measurement funnels contained in the set enable precise volumetric flow measurement at ventilation grilles. The calculated volumetric flow is shown directly on the vane anemometer's display. In addition, you can switch to the current temperature reading.
The direction of flow, i.e. inflow or outflow, is also shown on the display. Timed and multi-point mean calculations provide an indicator of the average volumetric flow, flow velocity and temperature readings. The vane anemometer shows min/max values and the hold function enables the current readings to be retained. The illuminated display allows you to carry out your measurements even in a dark environment.
This set means you are ready to get started: the testo 417 vane anemometer is simply attached to the testovent 417 measurement funnel for measurement at ventilation grilles or poppet valves. Once you have selected the measurement funnel factor on the vane anemometer, you can start your measurement.
The set comprises the testo 417 vane anemometer and the testovent 417 measurement funnels – one for poppet valves (diameter 200 mm) and one for ventilation grilles (330 x 330 mm). After the measurement, you can safely store or transport the measurement funnels in the bag.
