Description
Overview
The Testo 440 Air Flow ComboKit 2 with Bluetooth is designed for comprehensive air velocity and IAQ measurements in various HVAC applications. This versatile kit ensures precise data collection in ventilation ducts and at air outlets, making it an essential tool for HVAC professionals.
It combines the Testo 440 measuring instrument with both 100mm Bluetooth and 16mm wired vane probes. All components are safely stored in a durable combi-case, providing convenience and protection for on-site work.
Why It Matters
Accurate air flow and IAQ measurements are crucial for maintaining efficient and healthy indoor environments. This kit helps technicians diagnose ventilation issues, verify system performance, and ensure compliance with comfort standards, ultimately enhancing occupant well-being and energy efficiency.
What's Included
- Testo 440 air velocity and IAQ measuring instrument (0560 4401)
- Vane probe (Ø 3.9") with Bluetooth, including temperature sensor (0635 9431)
- Vane probe (Ø 0.63") with fixed cable and telescope (0635 9532)
- Combi-case for Testo 440 and multiple probes (0516 4401)
- 3 AA batteries, USB cable, and calibration protocols
Features & Benefits
- All-in-one Measurement: Intuitive menus for volume flow, air velocity, humidity, and temperature.
- Flexible Probes: Includes both 100mm Bluetooth vane for larger outlets and 16mm wired vane with telescope for ducts.
- Wireless Convenience: Bluetooth connectivity for hassle-free measurements and reduced cable clutter.
- Data Management: USB interface allows easy export of measurement reports as CSV files for analysis and documentation.
- Extendable System: Compatible with a wide range of additional probes for future versatility.
Applications
- Measuring air velocity and volume flow in ventilation ducts.
- Assessing air flow and temperature at ventilation outlets (grilles and diffusers).
- Conducting indoor air quality (IAQ) spot checks.
- Verifying HVAC system performance and balancing.
Tradie Pro Tip
"Always ensure your vane probes are properly calibrated for precise readings. When measuring in ducts, take multiple readings across the duct cross-section and average them for a more accurate volume flow calculation. Use the telescope with the 16mm vane for hard-to-reach areas."
