TESTO 440 Set anemometer (0563 4400)

The TESTO 440 Set Anemometer (0563 4400) combines a versatile handheld instrument with a 16 mm vane probe featuring a Bluetooth handle, enabling wireless measurement of air velocity, temperature, and volume flow. Unlike fixed-function meters, this set supports additional optional probes for humidity, CO2, CO, and differential pressure, making it adaptable to a wide range of HVAC and IAQ applications.

Highlights

• 16 mm vane anemometer with Bluetooth handle for flexible positioning
• Measures air velocity from 0.6 to 50 m/s with high accuracy
• Integrated differential pressure sensor up to ±150 hPa
• Large graphic display with backlight for clear readings
• Stores up to 7,500 measurement protocols

In daily use

The 440 Set Anemometer is built for HVAC technicians and facility managers who need reliable airflow measurements in ducts, at vents, or in open spaces. The Bluetooth vane probe allows you to measure without cable clutter, while the instrument's intuitive menu guides you through volume flow calculations with duct geometry input. Data can be transferred via USB for reporting and analysis.
