Use the vane probe with the matching testo multifunction meter (please order separately) to measure flow velocity; volume flow and temperatures up to +70 °C. High-precision vane probe with Bluetooth incl. temperature sensor – Features The measured values of the vane probe are transmitted to your measuring device up to a distance of 20 m via Bluetooth. The clearly structured measuring menu for volume flow enables intuitive operation of the measuring device. Thanks to convenient input of dimension and geometry of the duct cross-section, the volume flow is calculated exactly. Time and point averaging, average volumetric flow, current measured value and min/max values are displayed in the measuring device. Particularly practical: Press the button on the impeller probe and operate the measuring device. For example, to save individual measured values for point-by-point averaging or to start and stop measurement series for time averaging. Wireless and space-saving: more applications, less equipment Unlimited versatility: A universally applicable handle can be connected to all probe heads – so you can master more applications with less equipment and save space. The Bluetooth handle makes your measurements more comfortable and reduces cable clutter in the case. Or order the cable handle to connect testo probe heads. This is an advantage if Bluetooth signals are not allowed. If the impeller needs to be replaced in the distant future, you can replace the probe head. If required, equip the impeller probe additionally with the extendable telescope with 90° angle and, if necessary, the telescope extension (both can be ordered separately; in combination 2 metres long). This ensures convenient measurement at ceiling outlets. Intelligent calibration concept With the digital impeller probe, you benefit from particularly precise measurement results, as the measurement uncertainty from the meter is eliminated. For calibration, you only send in the probe head – so the measuring device remains in use throughout. Areas of application of the high-precision impeller probe with Bluetooth air/ceiling diffusers: With the impeller probe you can determine the flow velocity and volume flow at the air diffuser. The low start-up speed of 0.1 m/s makes the impeller probe ideal for laminar flow measurements in clean rooms. When looping the grid cross-section, the flow values are integrated and averaged over a large area of 100 mm. This allows precise measurement results to be achieved with the loop measurement. For measurements on ceiling diffusers: The extendable telescope (1.0 m long) with easy-to-read scaling and 90° angle can be effortlessly attached to the impeller probe. The 90° angle ensures the correct positioning of the probe under the ceiling. For high ceilings, you can also use the telescopic extension to achieve a total length of 2 metres (please order extendable telescope and telescopic extension separately). Poppet valves, ventilation grilles and swirl diffusers: For convenient and precise measurements on poppet valves and ventilation grilles, we recommend using the impeller probe with the funnel set testovent 417 (please order separately). This ensures easy testing of supply and extract air – such as in controlled residential ventilation. If the volumetric flow rectifier (please order separately) is added, an impressively high level of precision is achieved when measuring swirl diffusers.
