Testo 0554 0990 Telescope Extension

Overview

The Testo 0554 0990 telescope extension is used to easily extend the Testo telescope for air-velocity probes with a universal handle, achieving a total probe length of up to 2 m. This makes it ideal for reaching deep into ventilation ducts or up to high ceiling outlets where the standard telescope alone cannot reach. Lightweight at just 80 g and 12 mm in diameter, it adds reach without adding bulk.
