testo 440 Air Flow ComboKit 1 with Bluetooth in detail

• No task is too challenging, no application too specialized: the testo 440 combines a compact hand-held measuring instrument with intuitive measurement menus and a wide selection of air velocity and IAQ probes (please order separately)
• Clearly structured measurement menus for carrying out measurements in ventilation ducts/at duct outlets: the volume flow is precisely calculated thanks to convenient input of the size and geometry of the duct cross-section. Timed and multi-point mean calculation, average volume flow, current reading and min./max. values are displayed
• Other practical measurement menus, e.g. long-term measurement, volume flow measurement with a funnel, etc.
• Easy storage and evaluation of measurement data. Measurement data memory for up to 7500 measurement protocols, which can be read via a USB port and further processed as a CSV file on the computer (e.g. with Excel)
• Practical magnets for easy attachment of the measuring instrument to metal surfaces (e.g. ducts)
• Automatic detection of probes, e.g. vane probe, hot wire probe
• Large, backlit colour display

• Use the vane probe (Ø 100 mm) to easily determine air velocity, volume flow and air temperature at air/ceiling outlets
• Measuring range: +0.3 to +35 m/s, -20 to +70 °C
• More applications – less equipment: the universal handle on your 100 mm vane probe is easy to attach to other probe heads or telescopes. This allows you to expand your portfolio of probes and save space in the measuring case
• Carry out measurements at air/ceiling outlets effortlessly and without using a ladder: simply combine the vane probe with the optional, extendable telescope with 90° angle
• Wireless: the Bluetooth handle makes it more convenient to carry out your measurements and guarantees less cable clutter in the case
• Practical button on the handle: to store individual readings for multi-point mean calculation or to start and stop measurement series for mean calculation over time
• Our recommendation for carrying out accurate measurements at plate outlets/ventilation grilles: use the vane probe with the testovent 417 funnel set (available to order separately). If you add in the volume flow straightener (please order separately), you can achieve an impressively high level of precision when carrying out measurements at swirl outlets with turbulent air flow
• Intelligent calibration concept: the testo 440 air velocity and IAQ measuring instrument remains in continuous use, since only the probe head with 100 mm vane is sent in for calibration

• Use the hot wire probe to measure air velocity, volume flow and air temperature in ventilation ducts
• Accurate measurements from 0 to 30 m/s and -20 to +70 °C thanks to the robust sensor and automatic absolute pressure compensation
• Telescope that can be extended to 0.85 m, with scaling, makes it easy to measure in ventilation ducts
• Use the fixed cable to connect the hot wire probe to the measuring instrument
• Intelligent calibration concept: you only need to send in the hot wire probe for calibration, so the instrument can remain in continuous use
