Testo® 90° angle - for connecting paddle-wheel probes Ø100mm

Ideal for measurements on ceiling diffusers: The 90° angle ensures the correct positioning of the matching impeller probe on the ceiling diffuser. For high ceilings, in addition to the extendable telescope, also use the telescope extension (both can be ordered separately) - this allows you to achieve an overall telescope length of 2 meters. Clever: If you already own one of our flow probes with universal handle and extendable telescope, you can easily combine this telescope with one of the 100 mm impeller probes with universal handle. Simply add the optional 90° angle for measurements on ceiling outlets.
