Testo 440 Air Flow ComboKit 1 with Bluetooth

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!

Use this practical kit to handle all relevant measurements in ventilation ducts and at air outlets. The testo 440 multifunction measuring instrument, the vane probe and the hot wire probe including telescope all feature an intelligent calibration concept, ease of use and maximum convenience for the adjustment of air-conditioning and ventilation systems.

Features and Benefits

• Intuitive: clearly structured measurement menu for volume flow and parallel determination of air velocity, humidity and temperature in ventilation ducts or at ventilation outlets

• Clever: hot wire probe with telescope (0.85 m) – combine the vane probe (Ø 100 mm) with Bluetooth with the telescope for ceiling outlets or the funnel set for plate outlets (please order separately) as required

• Convenient: wireless probe, internal data storage and USB port for data export

• As multifaceted as your challenges themselves: the air velocity and IAQ measuring instrument can be expanded with a large portfolio of digital probes

Testo 440 air velocity and IAQ measuring instrument:

• 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

Vane probe (Ø 100 mm) with Bluetooth, including temperature sensor:

• 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

Hot wire probe including temperature sensor:

• 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
