  1. 1.0 m Extendable Length – Easily access deep or hard-to-reach ventilation ducts.
  2. Integrated Scaling – Clear, easy-to-read scale ensures accurate insertion depth for repeatable measurements.
  3. 90° Angle Adapter Included – Enables convenient positioning of 100 mm vane probes at ceiling outlets.
  4. Non-Rotating and Sturdy – Maintains consistent orientation during duct measurements.
    5. Telescopic extension up to 1 meter for flow probes, with integrated scale and 90° angle adapter for ceiling outlet measurements. Ideal for use in ventilation ducts.
    The Testo Extendable Telescope is the ideal accessory for professionals measuring air velocity and volume flow in ventilation and air conditioning systems. Extendable up to 1 meter, the telescope is designed for easy, stable insertion into ductwork. The integrated scaling along the shaft ensures consistent and accurate placement of your probe tip inside the duct.

    With the included 90° angle adapter, you can also take precise measurements at ceiling outlets, making this tool versatile and practical for a variety of HVAC applications.

    The telescope is non-rotatable, ensuring measurement stability and reliability. It is compatible with all Testo air velocity probe heads when connected to the universal handle (Bluetooth® or cable), using the handle adapter (Order No. 0554 2160).
