Product Overview & Benefits
The Testo 400 Air Flow Kit with 16 mm Vane Probe is a comprehensive solution designed for HVAC professionals conducting detailed airflow and Indoor Air Quality (IAQ) assessments. This kit features the versatile Testo 400 universal IAQ instrument, enabling precise measurement of critical climate parameters like flow velocity, temperature, humidity, differential pressure, CO₂, and CO.
Equipped with both 16 mm and 100 mm vane probes, along with a high-precision humidity/temperature probe, this kit supports a wide range of applications. All probes easily connect to the included Bluetooth® handle, ensuring convenient wireless operation and reducing cable clutter. It's the ideal tool for standard-compliant measurements in air ducts, meeting EN ISO 12599 and ASHRAE 111.
Key Kit Inclusions & Features
- Testo 400 Universal IAQ Instrument: Central hub for all measurements, with intuitive menu guidance.
- 16 mm Vane Probe Head: Perfect for precise airflow measurements within air ducts.
- 100 mm Vane Probe Head: Ideal for larger outlets and grid-based volume flow measurements.
- High-Precision Humidity/Temperature Probe Head: For accurate environmental condition monitoring.
- Bluetooth® Handle: Provides wireless connectivity for all included probe heads, enhancing flexibility.
- Telescopic Extension (up to 1.0 m) & 90° Angle: Enables ergonomic, ladder-free measurements at high ceiling outlets.
- Advanced Data Management: Includes PC software for streamlined report generation, analysis, and customer site organisation.
- Expandable System: Compatible with a broad range of digital Bluetooth® and cable probes for future measurement needs.
Tradie Pro Tip: For critical airflow measurements in larger ducts or at ceiling diffusers, always utilise the 100mm vane probe. Its larger diameter averages flow over a greater area, providing more representative volume flow readings than smaller probes.
