KEY FEATURES

• High-precision 100 mm vane probe designed for accurate airflow and temperature measurements
• Detects extremely low air velocities from 0.1 m/s for laminar flow and cleanroom validation
• Simultaneously measures air velocity, volume flow, and temperature
• Integrated NTC temperature sensor delivers accurate thermal measurements up to +70 °C
• Bluetooth® connectivity provides wireless data transmission up to 20 metres
• Compatible with Testo 400, 440, and 480 multifunction measuring instruments
• Ideal for HVAC balancing, laboratory ventilation testing, and controlled environment monitoring

The Testo 0635 9371 High-Precision Vane Probe with Bluetooth® is engineered for demanding airflow measurement applications requiring exceptional accuracy at very low air velocities. Designed around a precision 100 mm vane sensor, it delivers reliable measurements of air velocity, volume flow, and temperature across cleanrooms, laboratories, ventilation systems, and critical environmental monitoring applications. Its ability to accurately detect airflow from just 0.1 m/s makes it particularly suitable for laminar flow validation and controlled ventilation assessments. Wireless Bluetooth® communication allows flexible operation without cable restrictions, while compatibility with Testo multifunction measuring instruments and optional airflow accessories ensures dependable, repeatable, and standards-compliant measurement performance.

ADDITIONAL FEATURES

• Wireless Bluetooth® communication range up to 20 metres improves measurement flexibility
• Ergonomic handle includes integrated control button for data logging and measurement control
• Supports timed and multi-point averaging calculations for enhanced measurement accuracy
• Optional telescopic extensions enable convenient testing of ceiling-mounted outlets and diffusers
• Compatible with 90° angle adapters for difficult-to-access measurement locations
• Works with funnel and flow straightener accessories for improved outlet measurement precision
• Probe-head-only calibration concept minimizes maintenance downtime and operating costs

APPLICATIONS

• Ideal for cleanroom validation, laminar airflow verification, HVAC commissioning, ventilation balancing, laboratory airflow analysis, environmental monitoring, air outlet testing, controlled process environments, and commercial building airflow diagnostics.
