TESTO 440 - SET OF MULTIFUNCTION METER + VANE PROBE Ø100 MM 0563 4403

The intuitive and user-friendly multifunction measuring instrument TESTO 440 has been designed for professionals performing measurements in ventilation ducts and at air outlets. The device features a clear measurement menu that enables quick calculation of air volume flow as well as simultaneous measurement of air velocity, humidity, and temperature. This provides the operator with a complete overview of the air conditions at a given location without the need for complex configurations or additional calculations.

Measurement precision is ensured by the possibility of connecting a 100 mm vane probe with Bluetooth® communication. This probe can be mounted on a telescopic handle with a 90° angle adapter, allowing easy access even to hard-to-reach places. If measurements need to be taken deeper within the system, the telescope can be further extended (extension accessories available separately). This solution guarantees flexibility during work and maximum accuracy of results.

User comfort is enhanced by the probe’s wireless design and the instrument’s internal memory, which allows measurement results to be stored directly in the device. The collected data can be exported at any time via the USB port, streamlining the analysis and reporting process. A robust transport case is also included, protecting both the instrument and the probes during transport between job sites.

The TESTO 440 is also a truly multifunctional instrument – in addition to standard airflow velocity and indoor air quality measurements, it can be expanded with a wide range of digital probes tailored to individual requirements. This makes it a long-term investment that can be adapted to new tasks and demands. High accuracy, intuitive operation, and versatile expansion options make this device suitable for both everyday service measurements and advanced research applications.
