Product Description
The Testo 440 Air Flow ComboKit 2 with Bluetooth is an integrated industrial instrumentation solution engineered for comprehensive diagnostics within ventilation ducts and at air outlets. This professional hardware kit combines the Testo 440 multi-function master instrument with a digital 16 mm vane probe (featuring an integrated 0.85 m telescope) and a wireless digital 100 mm vane probe with integrated Bluetooth. The system enables simultaneous parallel logging of air velocity, volumetric flow rate, and thermal properties, utilizing structured internal storage and direct USB export interfaces.
Industry Applications
- HVAC System Commissioning: Measuring aerodynamic profiles and balancing volume flow rates in distribution ducts and extraction grilles.
- Commercial Building Commissioning: Conducting structured indoor air quality (IAQ) and air exchange efficiency audits across public infrastructures.
- Industrial Cleanroom Certification: Precise verification of laminarity, environmental safety boundaries, and micro-climate parameters.
