The invention discloses device and method for measuring gas specific heat ratio. The device comprises a first gas storage bottle, a second gas storage bottle, a U-shaped pipe with scales, an inflating ball, a pressure sensor, a data measuring and processing system, four bottle plugs, four three-port glass delivery tubes, a two-port glass delivery tube, a fixed seat and six cock-type air valves. In the method, the gas specific heat ratio is obtained according to an adiabatic equation of gas by detecting the parameters of the U-shaped pipe and the gas storage bottles under different statuses. The invention is rapid and convenient to measure.

The invention discloses a wireless measuring method for a direction field, wherein a probe is integrated with a moving mechanism in a wireless transmission manner. The moving mechanism drives the probe to realize omnidirectional movement on a same cross section, thereby realizing continuous measurement without stoppage of air blowing through a wind tunnel. According to the probe of the invention, the number of pressure testing tubes which are exposed to outside is reduced, and pipe laying operation in traditional testing is prevented, and real-time test is completed in a more direct manner.
