Testo 417 F-Reg Anemometer Kit

The Testo 417 F-Reg Kit is designed to make compliance simple for the installer; the Testo 417 measures and displays the volume flow at a touch of a button, without the need for complicated grill size calculations. Two funnel sizes are included in the set, ensuring simple flow capture for both circular and square grills.

In England and Wales, requirements for ventilation are contained in Approved Document F and can be downloaded from planningportal.gov.uk. The Building Regulations Approved Document F 2010 considers ventilation through a combination of infiltration and purpose-provided ventilation. Regulations are constantly being reviewed, with the aim to improve building standards, so it is worth checking the Planning Portal website for any updates to Building Regulations.

The F-Reg kit comes supplied with a UKAS Calibration certificate to ensure accuracy of the readings.

The testo 417 is a compact, large-area anemometer with a built-in flow velocity / temperature vane. It measures flow velocity, volume flow and temperature. Thanks to the integrated measurement with the 100 mm vane, it is ideally suited for measurements at air input and output vents. The flow direction, i.e. blowing or sucking flow, is visible in the display. The optimum funnel set additionally allows measurements on ventilation grilles and disc outlets.

The volume flow is directly shown in the display. For the purposes of volume flow calculation, the duct area can be easily entered into the testo 417. In addition to this, the instrument can be switched over to display the current temperature.Timed and point mean value calculation provide information on the average volume flow, flow velocity and temperature measurement value. The Hold function allows the current measurement value to be frozen in the display, min./max. values are also displayed at the press of a button.

The compact anemometer testo 417 with integrated flow/temperature vane (Ø 100 mm) is ideal for measuring the flow velocity, volumetric flow and temperature at duct outlets. The optional funnel set allows measurements at ventilation grilles and poppet valves.
