Zoom | Type-No.: 8420.0000
Windtunnel
The windtunnel type 8420 is basicly designed as test equipment for calibration of wind sensors. The open construction with the measuring section in the suction part enables compact dimensions and therefore operation in relatively small rooms. An SCR controlled DC motor drive enables a wide operation range and stable rotational speed. Depending on customer’s specification different reference equipment (Differential pressure gauges, Thermal anemometers as well as Laser-Doppler Anemometers) and accessories (Test adapters, PC’s, Printers, Monitors etc.) are available. Custom made software solutions for semi- or fully- automatic operation incl. print out of final test reports can be offered.
