Hot Wire Anemometer with Telescopic ProbeHandheld Hot Wire Anemometer is a compact, accurate and robust device for measuring air velocity, volume, flow and temperature. Telescopic hot wire probe is designed to minimize the turbulence effect for in duct measurements, and is well suited for low flow applications. The probe features a rubberized ergonomic grip and extends retracts from 10 to 38 inches. Timed and multi point average flow calculations and in duct air balancing with fast response
