What is the Testo testovent 417 Flow Straightener Set?
The Testo testovent 417 flow straightener set is a specialist airflow measurement accessory designed for UK HVAC engineers and ventilation technicians carrying out volume flow measurements at swirl outlets, grilles and plate diffusers. It converts turbulent airflow into a stable, measurable stream, ensuring accurate and repeatable readings.
Ideal for professionals searching for airflow measurement accessories, ventilation testing tools or volume flow measurement kits in the UK, this solution improves reliability when balancing and commissioning HVAC systems.
How does the testovent 417 improve airflow measurements?
Swirl outlets create turbulent air patterns that can lead to inconsistent readings when using standard vane anemometers. The patented Testo flow straightener redirects airflow into a uniform stream, allowing precise and stable measurements.
Paired with two dedicated funnels for different outlet types, this set ensures accurate volume flow readings across a wide range of ventilation applications, helping engineers achieve correct system balancing and performance.
How does it stand out in everyday use?
The testovent 417 offers a simple yet highly effective way to eliminate airflow turbulence, improving measurement confidence without complex setup. It is a practical solution for engineers who need reliable results when working with challenging ventilation outlets.
