Product Description
The Testo 440 Air Flow ComboKit 1 with Bluetooth is a professional engineering instrumentation solution designed for comprehensive diagnostics within ventilation ducts and at air outlets. This hardware kit combines the Testo 440 multi-function master instrument with a digital hot wire probe (including an 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 air temperature, utilizing structured internal storage and direct USB export interfaces.
Industry Applications
- HVAC Performance Diagnostics: Measuring aerodynamic profiles and balancing volume flow rates in main distribution ducts and ceiling diffusers.
- Commercial Building Commissioning: Conducting structured indoor air quality (IAQ) and air exchange efficiency audits across industrial buildings.
- Industrial Cleanroom Certification: Precise verification of laminarity, environmental safety boundaries, and micro-climate parameters.
