Description
Overview
The Testo 440 dP Air Flow ComboKit 1 provides a comprehensive solution for HVAC professionals, enabling precise air flow measurements without the hassle of cables. This kit is specifically designed for all relevant measurements in ventilation ducts and at air/ceiling outlets.
It includes the Testo 440 dP air velocity and IAQ measuring instrument with a differential pressure sensor. Complementing this are a 100 mm vane probe head and a 9 mm hot wire probe head, both attachable to the universal Bluetooth handle. For extended reach and flexibility, these probe heads can be combined with the included 1.0 m extendable telescope.
Why It Matters
Accurate air flow and indoor air quality (IAQ) measurements are fundamental for ensuring optimal HVAC system performance, energy efficiency, and occupant comfort. This kit empowers tradies to quickly identify issues, verify system parameters, and comply with ventilation standards, leading to healthier indoor environments and reduced operational costs.
What's Included
- Testo 440 dP Air Velocity and IAQ Measuring Instrument with Differential Pressure Sensor (0560 4402)
- 100 mm Vane Probe with Bluetooth® including Temperature Sensor (0635 9431)
- Hot Wire Probe Head (Ø 9 mm) including Temperature and Humidity Sensor (0635 1570)
- Extendable Telescope (up to 1 m in length) for Flow Probes (0554 0960)
- Combi-case for Testo 440 and Multiple Probes (0516 4401)
- Connection Hose, AA Batteries, USB Cable, and Calibration Protocols
Features & Benefits
- Versatile Measurement: Handles all climate-related parameters, including air velocity, volume flow, differential pressure, humidity, and temperature.
- Intuitive Operation: Clearly structured measurement menus simplify setup and execution for various tasks.
- Wireless Convenience: Bluetooth® probes allow for flexible and cable-free measurements, improving accessibility.
- Extendable Reach: Combine probe heads with the 1.0 m telescope for measurements in hard-to-reach ducts and outlets.
- Data Management: USB interface enables easy export of measurement reports as CSV files for documentation and analysis.
- Robust Transport: Safely store and transport all components in the durable combi-case.
Applications
- Volume flow measurement in ventilation ducts and at air/ceiling outlets.
- Simultaneous determination of air velocity, differential pressure, temperature, and humidity.
- IAQ monitoring and assessment in commercial and residential buildings.
- Commissioning and maintenance of HVAC and ventilation systems.
Tradie Pro Tip
When conducting detailed air flow assessments, always utilise the extendable telescope with both vane and hot wire probes. This ensures consistent, accurate readings in hard-to-reach ducts and prevents measurement interference from your body, streamlining your diagnostic process.
