Testo 440 speed and indoor air quality meter makes air quality and speed measurements simple. Ideal for measuring the amount of flow and degree of turbulence and for mould detection.
Testo 440 speed and indoor air quality measuring device:
- Accurate and reliable in ducts and air outlets
- Performs turbulence measurements in accordance with EN ISO 7730 / ASHRAE 55 standards
- A wide range of connecting probes is available: the hot wire and paddle probe (Ø 16 mm) is ideal for measurements in ducts, while the large paddle probe (Ø 100 mm) is ideal for air/ceiling ventilation systems
- Automatically calculates the flow rate: by entering the cross-sectional dimensions or area of the duct, the flow rate measurement value is calculated
- Takes measurements in extra-large channels: a telescope with a hot-wire and paddle probe (Ø 16 mm) can reach lengths up to 2 metres
- Takes measurements without the need for a ladder: by attaching a paddle probe (Ø 100 mm) with a retractable telescope, lengths of up to 2 metres are achieved. Also, the vane probe can be folded up to 90°
- Determines the direction of flow (in or out) in the ventilation grille – using a vane probe, hoods and an airflow straightener
- Starts or stops measurement, saves data at the touch of a button
- Attaches to magnetic surfaces with magnets on the back of the device
- Performs long-term monitoring of indoor air quality
