For measurements in fume cupboards: use the fume cupboard probe (with the compatible measuring instrument) to measure air velocity, volume flow and air temperature.The hot ball probe (in conjunction with the appropriate measuring instrument) is ideal for determining flow velocity and temperature.For measurements in ventilation ducts: use the hot wire probe (with the compatible measuring instrument) to measure air velocity, volume flow and air temperature.The hot wire probe (in conjunction with the appropriate measuring instrument) is ideal for determining flow velocity and temperature in ventilation ducts or at plate outlets and ventilation grilles.For determining the degree of turbulence and draught risk at workplaces: use the turbulence probe (with the compatible measuring instrument) to measure air velocity and air temperature.The compact vane anemometer testo 417 in a kit incl. two measurement funnels was developed to make it as easy as possible for you to take measurements on air inlets and outlets as well as plate outlets of air conditioning and ventilation systems. The integrated 100 mm vane quickly ensures precise results. Time and point average values as well as the volume flow are automatically calculated in the instrument and shown on the display. This allows balanced residential ventilation systems to be adjusted particularly efficiently - including quick documentation with the testo Smart App.
In addition, the App not only supports you in configuring the measuring instrument and takes over display, storage and documentation of the measured values – it also turns your smartphone into a second display. The testo 417 Kit 1 includes two measuring funnels for plate outlets and ventilation grilles. These can be easily attached to the vane, covering a wide range of outlet sizes and formats.The compact vane anemometer testo 417 in Kit 2 including two measurement funnels and a flow straightener was developed to make it as easy as possible for you to take measurements on air inlets and outlets as well as plate and swirl outlets of air conditioning and ventilation systems. The integrated 100 mm vane quickly ensures precise results. Time and point average values as well as the volume flow are automatically calculated in the instrument and shown on the display. This allows balanced residential ventilation systems to be adjusted particularly efficiently - including quick documentation with the testo Smart App.
In addition, the App not only supports you in configuring the measuring instrument and takes over display, storage and documentation of the measured values – it also turns your smartphone into a second display. The testo 417 Kit 2 includes two measuring funnels and a volume flow straightener for precise results even at swirl outlets.Kit for carrying out measurements in ventilation ducts and at air outlets: The testo 440 air velocity and IAQ measuring instrument, the vane probe (Ø 100 mm) with Bluetooth^® including temperature sensor and the hot wire probe including temperature sensor are all safely stowed away in the case. So you can get down to work straight away!Kit for carrying out measurements in ventilation ducts: the testo 440 air velocity and IAQ measuring instrument and the hot wire probe (Ø 9 mm) including temperature sensor are all safely stowed away in the case. So you can get down to work straight away!Use this practical Indoor Comfort ComboKit to handle all relevant measurements in order to evaluate the indoor air quality in indoor areas and to determine the draught risk and degree of turbulence in workplaces. The testo 440 air velocity and IAQ measuring instrument, the CO₂ probe with Bluetooth^® including temperature and humidity sensor and the turbulence probe are all safely stowed away in the case. So you can get down to work straight away!Ideal kit for IAQ professionals, with a focus on indoor air quality and comfort level. You will receive the testo 400 universal IAQ measuring instrument with intuitive measurement menus, one CO₂ probe (with Bluetooth^® handle), one turbulence probe and one globe thermometer Ø 150 mm (both with fixed cable). Use the measuring tripod to ensure standard-compliant positioning of the probes. In combination with the IAQ data logger, which is available to order separately, long-term measurements up to 2 weeks can be recorded, even without the IAQ measuring instrument.The compact 100 mm vane anemometer testo 417 is the ideal solution for simple, fast and precise determination of flow velocity and volume flow at air intake and outlet vents of air conditioning and ventilation systems. Adjustment for balanced residential ventilation or measurement at swirl outlets is also child's play with the testo 417 kits including funnel and flow straightener. Thanks to the connection to the testo Smart App, configuration, display (also as second screen) and storage as well as documentation of the measured values are dealt with quickly and without any complications.The compact hot wire anemometer testo 425 with telescopic probe is ideal for simple, fast and precise determination of flow velocity and volume flow in ventilation ducts of air conditioning and ventilation systems. The connection to the testo Smart App enables configuration, display (also as second screen) and storage as well as documentation of the measurement directly in the App.This ISO calibration certificate certifies that your measuring instrument or probe is calibrated. Calibration is carried out according to the ISO standard.
