The Climomaster Velocity & Temp Probe 6542-2G from Kanomax measures air velocity and air temperature when used in conjunction with the Climomaster Hot Wire Anemometer. This omni-directional probe can be oriented any way in the duct and still yield accurate air velocity measurements. The 6542-2G is capable of taking air velocity measurements from 20 to 6000 fpm and air temperature measurements from -4 to 158 °F.
