Increase the reach of your air velocity measurement equipment with this extendable telescope from Testo. It connects to flow probes in the 440 series for ease of assembly. Thanks to its extendable length of 350mm to 1m, it gives you better access to hard-to-reach places for more accurate readings. An angled connector helps you to take readings in awkward spaces, such as vents, ducts and ceiling outlets.

• Easy-to-read scale for precise positioning in ducts
• Stable and non-rotating telescope arm holds probe steady while in use
• Wide operating temperature range between -5°C and +50°C for use in demanding environments

• Heating and ventilation ducts
• Air conditioning units
• Environmental tests

Use the compatible handle adapter (176-5623) to easily connect this telescope to your probe.
