Features：

1) Attachable measurement funnels make it ideal for volumetric flow measurement at ventilation outlets

2) Simple testing of incoming / outgoing air in controlled ventilation of living spaces

3) Important accessories included in the set: measurement funnels for poppet valves and ventilation grilles, along with a bag for storage Make sure you get the testo 417 vane anemometer with an integrated 100 mm vane, in a set that includes two measurement funnels and other accessories. This will mean you are ideally equipped for volumetric flow measurement at ventilation grilles and poppet valves.

Product Description：

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.

This is What the Testo 417 Vane Anemometer Offers

 The testo 417 vane anemometer with an integrated 100 mm 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.
