The U.S. Army TMDE Activity requires two wind tunnels to support OCONUS calibration of hot-wire anemometers, helping reduce turnaround times for industrial hygiene and chemical testing facilities. The tunnels must generate air speeds from 1.5 to 50 m/s with measurement uncertainty =0.75%, turbulence intensity =1%, and test chamber cross-sections between 4x4 and 12x12 inches, while fitting through a standard 32-inch door and operating on 220V 16A single phase. Support includes delivery to TMDE Support Centers in Kaiserslautern, Germany and Camp Carroll, South Korea, along with organic calibration procedures and software that requires no subscription, can report standard and actual wind speed, correct for pressure/temperature, and export test data.
