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

Convenience and maximum flexibility for duct and outlet measurements
Use our large range of air velocity probes (please order probes that are not included in the kit separately) to carry out simple, convenient measurements even at locations that are difficult to access in ventilation ducts or at air outlets:

You can even carry out easy measurements in particularly large ducts. This is because the extendable telescope on the hot wire and vane probe (Ø 16 mm) with universal handle can be further extended using the telescope extension – enabling you to attain a total length of 2 metres.

Carry out measurements at air/ceiling outlets effortlessly and without using a ladder. Fit your vane probe (Ø 100 mm) with the telescope with 90° angle and, if necessary, with the telescope extension (both can be ordered separately).

Greater freedom thanks to Bluetooth: the air velocity probes with Bluetooth have no inconvenient cable connection to the measuring instrument, and they transmit readings up to a distance of 20 m. Press the button on the probe to operate the measuring instrument – for example, to start and stop a series of measurements (timed mean calculation).

Attach the testo 440 dP air velocity and IAQ measuring instrument to metal surfaces (e.g. ducts) easily using the practical magnets.

Benefit from fast calculation of the volume flow: in the “volume flow” measurement menu of the multifunction measuring instrument, configure the dimensions and geometry of the duct cross-section – the measuring instrument shows you the volume flow straight away.

Long-term monitoring of indoor air quality
Poor indoor air quality due to excessive concentrations of CO2 can cause tiredness, lack of concentration and even illness. With its menu for recording readings, the testo 440 air velocity and IAQ measuring instrument is ideal for monitoring the indoor air quality. Enter the measurement time and the measuring cycle – and, for example, track the change in CO2 concentration or humidity and temperature values over the course of the day. Simply choose between probes with Bluetooth or fixed cable for CO2, CO or humidity (please order probes separately).

Turbulence measurement in accordance with EN ISO 7730 / ASHRAE 55
Determine the degree of turbulence and the draught risk in the workplace: draught restricts the comfort level and is the most common cause of complaints about the indoor climate. The turbulence probe (please order separately) measures air velocity and air temperature, and automatically calculates the draught risk and the degree of turbulence in accordance with EN ISO 7730/ASHRAE 55.
For convenient measurements at varying heights, we recommend using our measuring tripod for comfort level measurement (please order separately). This makes it very easy to position turbulence probes in compliance with the standards.

Range of probes for cleanrooms and laboratories
The testo 440 air velocity and IAQ measuring instrument is also ideal for a wide variety of applications in cleanrooms and laboratories in conjunction with the following probes (please order separately):

• High-precision air velocity measurement on fume cupboards with the fume cupboard probe
• Thanks to the low start-up speed of 0.1 m/s, the high-precision vane probe (Ø 100 mm) is ideal for laminar flow measurements in cleanrooms. It is available as a variant with Bluetooth or with fixed cable
• To measure the humidity in cleanrooms, we recommend the high-precision humidity/temperature probe (0636 9771 or 0636 9772). With an accuracy of: ±(0.6% RH + 0.7 % of m.v.) (0 to 90% RH), it also meets the requirements for humidity measurements in this particularly sensitive area
