Product Description

Use this practical kit to measure air velocity, volume flow and air temperature at air outlets. The testo 440 multifunction measuring instrument and the vane probe feature an intelligent calibration concept, ease of use and maximum convenience for the adjustment of air-conditioning and ventilation systems.

testo 440 100 mm Vane Kit 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: the volume flow is precisely calculated thanks to convenient input of the surface area of the air outlet. 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
Large, backlit colour display

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

Use the vane probe (Ø 100 mm) to conveniently determine air velocity, volume flow and air temperature at air/ceiling outlets
Measuring range: +0.3 to +35 m/s, -20 to +70 °C
Endlessly versatile: a universal handle can be connected to all probe heads – so you can take care of more applications using less equipment, and save space too
The Bluetooth handle makes it more convenient to carry out your measurements and guarantees less cable clutter in the case. It transmits the readings to the testo 440 air velocity and IAQ measuring instrument, from up to 20 m away
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 convenient measurements at ceiling outlets: if required, you can also fit the vane probe with the extendable telescope with 90° angle and, if necessary, the telescope extension (both can be ordered separately; in combination 2 m long)
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 100 mm vane probe head is sent in for calibration
