Testo 440 set 16 mm vinghjulsanemometer (0563 4401)

This air velocity and IAQ meter set combines the Testo 440 dP differential pressure meter with a 16 mm vane probe for precise air velocity measurement from 0.6 to 50 m/s. The graphic display and internal memory for 7500 measurement protocols make it suitable for HVAC and cleanroom applications.

Advantages

The vane probe offers high accuracy of ±(0.2 m/s + 1.5 % of mv) and a resolution of 0.01 m/s. Bluetooth and USB connectivity enable data transfer to the Testo Smart App. The meter operates on 3 AA batteries with approximately 12 hours of battery life.

Suitable for

• HVAC system testing and balancing
• Cleanroom certification
• Indoor air quality assessments
• Differential pressure measurements with optional probes
