Testo 440 Air Velocity & IAQ Measuring Instrument (Choice of Version)

Testo 440 Air Velocity & IAQ Measuring Instrument

The Testo 440 Air Velocity & IAQ Measuring Instrument is a versatile tool designed to simplify the measurement of air velocity and indoor air quality parameters. With the option to choose between the standard model or a version equipped with an integrated differential pressure sensor (Testo 440 dP), it offers flexibility to suit various applications in HVAC systems, cleanrooms, and laboratories. The device features intuitive measurement menus for tasks such as volume flow, turbulence degree, and long-term indoor air quality monitoring.

With the ability to connect up to three probes simultaneously, including Bluetooth®, wired, and thermocouple probes, the Testo 440 ensures seamless operation. Automatic probe detection eliminates the need for manual settings adjustments, streamlining the measurement process and reducing time spent on configuration. This efficient tool helps professionals achieve accurate results with minimal effort.

Wireless Convenience and Efficient Data Management

The Bluetooth® connectivity enhances user experience by reducing cable clutter and allowing for remote measurements up to 20 metres away. The multifunctional handle is compatible with various probe heads, enabling more applications with fewer tools. This space-saving design makes it an ideal choice for professionals who need to perform a wide range of tasks.

The Testo 440 can store up to 7,500 measurement protocols, which can be exported as CSV files through its USB port. Additionally, the optional Testo BLUETOOTH/IRDA printer enables on-site report generation, adding to the convenience of this all-in-one measuring instrument.

For long-term monitoring, the device offers reliable solutions for CO₂, CO, temperature, and humidity measurements. Its intelligent calibration system ensures that only the probes need calibration, allowing the instrument to remain in continuous use without compromising on accuracy.

Whether you’re working in ducts, cleanrooms, or on ventilation systems, the Testo 440 provides precise and reliable results. The optional differential pressure sensor model (Testo 440 dP) is perfect for additional measurements such as Pitot tube readings and filter checks. Both models offer exceptional value and are built to handle the demands of professional use.

Choose the Testo 440 Air Velocity & IAQ Measuring Instrument for a reliable, user-friendly solution that adapts to your needs, whether you require the standard model or the differential pressure (dP) version.
