Product Description

Use this practical kit to handle all relevant measurements in ducts and at air outlets. The testo 440 multifunctional measuring instrument, the vane probe (Ø 100 mm) with Bluetooth and the vane probe (Ø 16 mm) including extendable telescope all feature an intelligent calibration concept, ease of use and maximum convenience for the adjustment of air-conditioning and ventilation systems.

testo 440 Air Flow ComboKit 2 with Bluetooth in detail

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 (Ø 100 mm) and vane probe (Ø 16 mm)
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 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
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
For measurements at ceiling outlets: simply combine the vane probe with the optional, extendable telescope (1.0 m long) with 90° angle
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

Vane probe (Ø 16 mm):

Use the vane probe to measure air velocity and volume flow in ventilation ducts
Measuring range from 0.6 to 50 m/s
Telescope that can be extended to 0.85 m makes it easy to measure in ventilation ducts. Easy-to-read immersion depth thanks to scaling on the telescope
Use the fixed cable to connect the vane probe to the measuring instrument
Intelligent calibration concept: You only need to send in the vane probe for calibration
