The testo 440 Set is an effective measuring device to determine the flow speed, volume flow and air temperature in the ventilation ducts. The testo 440 Set contains a compact hand-held meter, a hot-wire probe (Ø 9 mm) included temperature sensor with telescope. The testo 440 hand-held measuring device is supplied with batteries and is ready for use. A suitable combination case is included. The meter has a large, illuminated colour display and has a structured measurement menu and specific temporal averaging, average volume flow, current measured value, as well as min/max values are displayed. The dimension and geometry of the channel cross-section must be entered to calculate an exact calculation of the volume flow. Other measurement menus such as long-term measurement and volume flow measurement with funnel are also possible. The testo 440 meter collects and evaluates your measurement data and up to 7,500 measurement protocols may be used in its integrated measurement data memory. https://elecena.pl/product/28140379/testo-0563-4400-testo-440-set-anemometer 2025-03-30 https://elecena.pl/product/28140379/testo-0563-4400-testo-440-set-anemometer 2025-05-15 https://elecena.pl/product/28140379/testo-0563-4400-testo-440-set-anemometer 2025-08-19 https://elecena.pl/product/28140379/testo-0563-4400-testo-440-set-anemometer 2025-09-30 https://elecena.pl/product/28140379/testo-0563-4400-testo-440-set-anemometer 2025-10-21 https://elecena.pl/product/28140379/testo-0563-4400-testo-440-set-anemometer 2025-12-03 https://elecena.pl/product/28140379/testo-0563-4400-testo-440-set-anemometer 2026-03-07 https://elecena.pl/product/28140379/testo-0563-4400-testo-440-set-anemometer 2026-03-31
