Benefits Comprehensive IAQ Measurement – Measures all IAQ parameters, including flow velocity, temperature, humidity, pressure, CO2, CO, and more. Parallel Parameter Detection – Measures volume flow, air velocity, humidity, and temperature simultaneously at air outlets. User-Friendly Operation – Intuitive, structured menus simplify measurement workflows and reduce setup time. Smart Data Handling – Stores up to 7500 readings and enables report exports via USB as CSV files for easy analysis. Description Designed for efficient airflow measurement at air outlets and ventilation systems, the testo 440 100 mm Vane Kit with Bluetooth® combines precision, convenience, and flexibility. The kit features the testo 440 multifunction IAQ measuring instrument and a high-quality 100 mm vane probe with Bluetooth® and integrated temperature sensor.The intuitive measurement menu guides you through volume flow calculations and parallel measurements of velocity, humidity, and temperature—making it ideal for balancing HVAC systems, verifying outlet performance, or conducting indoor air quality assessments.Thanks to wireless Bluetooth® connectivity, measurements are easy to carry out even in hard-to-reach areas, with less cable clutter. The probe can also be combined with optional accessories like the extendable telescope or funnel set for plate outlets, expanding your application range. Plus, the testo 440 is compatible with a wide variety of additional digital probes for comprehensive climate monitoring.Data can be stored directly on the instrument (up to 7500 readings) and exported as CSV files via USB for easy reporting and analysis. Delivery Scope testo 440 air velocity and IAQ measuring instrument, 3 x AA batteries, USB cable and calibration protocol (0560 4401) Vane probe (Ø 100 mm) with Bluetooth® including temperature sensor (consisting of 100 mm vane probe head, handle adapter and Bluetooth® handle); bracket for testovent measurement funnel; 4 x AA batteries and calibration protocol (0635 9431) Basic case for testo 440 and 1 probe
