Air conditioning and ventilation systems operate at maximum efficiency when air or volume flows in ducts and at outlets meet the proper specifications. With the versatility testo 440 kits have to offer, you can now take care of both measuring tasks more conveniently than ever before.
Air Velocity Measurement in Ducts and at Outlets
- Intuitive measurement menus
The testo 440 comes programmed with clearly structured menus for volume flow in ducts and at outlets, K factor, and pitot tube measurement.
- Convenient measurement
Telescoping probes with easy to read scaling make duct work a breeze.
They can be extended up to 6.6 feet.
- Versatile accessories
Extendable probes allow you to reach ceiling outlets with ease, and the funnels are perfect for plate outlets. Use the air flow straightener to measure turbulent flows with precision.
- Low maintenance instrument
Only the individual probe heads need to be calibrated. You can use the measuring instrument and handle with a variety of interchangeable probes.
Perform any air velocity measurement with ease
- Measurements in ducts – precision in any cross-section
- Measurements at outlets – achieve the ideal climate in next to no time
- Measurements of turbulent air flows – no task is too challenging
