The Testo Telescope Extension is the perfect solution when your air velocity measurements require extended reach. Designed for use with the Testo extendable telescope (0554 0960), this add-on allows you to expand the total probe length to up to 2 meters.

Ideal for accessing deep ventilation ducts, ceiling outlets, or elevated systems, the extension is quick to attach, non-rotating, and ensures accurate and consistent readings even at maximum extension.

This sturdy accessory is built for field use and is compatible with Testo flow probes mounted on a universal handle (Bluetooth® or cable), offering maximum flexibility for HVAC technicians.
