Open jet wind tunnel 
 I. Introduction 
 CRB-60 mining the open wind tunnel can be quickly and accurately provide the standard wind speed of 0.2-30M / S, is mainly used for wind table, wind speed sensors, as well as other gas flow meter calibration, meteorology, metrology, coal, industrial and other sectors test wind speed instrument of the specialized legal measuring instruments. 
 The wind tunnel with two rectifier, small size, high stability, smooth, open and wide range of applications. Wind tunnel using a small volume multi-leaf fan, high-performance frequency control, easy to use, low noise, fast action clamping agencies can quickly replace the orifice, an adjustable bench, quickly install the instrument, a simple adjustment, high efficiency wind tunnel comes with bracket, landing can use, easy to install.
