Description
The testo 440 stores up to 7,500 measurement protocols, which can be read via USB port and further processed as a CSV file on your computer (e.g. with Excel). With the testo Bluetooth / IrDA printer (sold separately), you have the ability to produce a printed report of measurement data directly on site.
Intelligent calibration concept for maximum precision
You can rely on the accuracy of your measurement results with our digital probes, because the testo 440 makes measurement uncertainty a thing of the past. You only need to send the probes in for calibration, meaning the multifunction instrument can remain in continuous use with a variety of interchangeable probes.
Advantages of measuring with the testo 440 air velocity and IAQ measuring instrument
Long-term monitoring of indoor air quality
Turbulence measurement in accordance with EN ISO 7730 / ASHRAE 55
Wide range of probes for laboratories and cleanrooms
