Product Description
The Testo 440 16 mm Vane Kit is an integrated engineering solution designed for structured diagnostic logging within ventilation ducts. This hardware combination features the Testo 440 multi-function air velocity and IAQ master instrument alongside a digital vane probe (Ø 16 mm) with an integrated temperature sensor. The system facilitates parallel calculation of volumetric flow, air velocity, and thermal properties, backed by automated internal data storage and a USB data export interface.
Industry Applications
- HVAC System Commissioning: Balancing structural volume flow and verifying design compliance within industrial ventilation architectures.
- Commercial Facility Management: Regular indoor air quality (IAQ) audits and air exchange velocity mapping across corporate infrastructures.
- Industrial Cleanroom Maintenance: Technical monitoring of laminarity and thermal behavior in strict production environments.
