The 90° Angle Adapter is designed for optimal positioning of 100 mm vane probes with universal handles when measuring at ceiling outlets. This practical accessory allows you to connect your vane probe at a right angle to your extendable telescope, ensuring proper alignment with the airflow direction.

Ideal for use in HVAC testing where air outlets are difficult to access, the 90° adapter helps achieve accurate readings without compromising on ergonomics or reach.

When working in high-ceilinged environments, combine this adapter with the Testo extendable telescope (0554 0960) and telescope extension (0554 0990) to reach up to 2 meters – making it a must-have tool for ventilation professionals.
