Product Description:

Use this practical kit to measure air velocity and volume flow in ventilation ducts. The testo 440 multifunction measuring instrument and its vane probe are low maintenance, easy to use, and maximize convenience when adjusting air conditioning and ventilation systems.

Intuitive: Clearly structured measurement menus for volume flow and determination of air velocity in ventilation ducts
Convenient: Integrated telescope with scaling can be extended up to 2.8 feet, making it easy to carry out all kinds of measurements
Reliable: Internal memory for data storage and USB port for data export
Versatile: Your testo 440 setup can be expanded with a large selection of digital probes

This testo 440 kit is great for carrying out measurements in ventilation ducts. The testo 440 air velocity and IAQ measuring instrument and its vane probe (Ø 0.63") can all be safely stored in the included case.

The testo 440 vane kit in detail

testo 440 air velocity and IAQ measuring instrument:

No task is too challenging, no application too specific – the testo 440 combines a compact handheld measuring instrument with intuitive measurement menus and a wide selection of air velocity and IAQ probes (probes sold separately)
Clearly structured measurement menus – volume flow is calculated precisely, thanks to convenient inputs for the size and geometry of a duct's cross-section. Displays timed and multi-point mean calculation, average volume flow, current reading, and maximum / minimum values
Other practical measurement menus, e.g. long-term measurement, volume flow measurement with a funnel, etc.
Easy storage and evaluation of measurement data – internal memory for up to 7,500 measurement protocols, which can be read via USB port and further processed as a CSV file on the computer (e.g. with Excel)
Practical rear magnets for secure attachment of the measuring instrument to metal surfaces (e.g. ducts)
Automatic detection of probes, e.g. vane probe
Large, backlit color display

Vane probe (Ø 0.63"):

Use the vane probe to measure air velocity and volume flow in ventilation ducts
Measuring range from 118.1 to 9843 fpm
Integrated telescope with scaling can be extended up to 2.8 feet, making it easy to carry out measurements in ducts
Use the fixed cable to connect the vane probe to the testo 440
Intelligent calibration concept – the testo 440 remains in continuous use, since only the individual probes need calibration
