Measurement gun for measuring smoke linear flow velocity and smoke temperature field in combined smoke channel

The utility model relates to a measurement gun for measuring the smoke linear flow velocity and smoke temperature field in a combined smoke channel and belongs to the field of environmental monitoring instruments. The measurement gun is mainly used for synchronously measuring the smoke flow velocity and smoke temperature of each point in smoke channels according to the sectional area of different smoke channels. More than four pairs of S-shaped pitot tubes and temperature sensors are combined with each other so as to form the measurement gun; the interval between measuring holes of the measuring heads of each of the S-shaped pitot tubes is 200mm; each S-shaped pitot tube is bent by an angle from 5 degrees to ten 10 degrees at a position which is separated from a corresponding measuring head by 100 mm; and after the bending, the central line of the measuring head is parallel to the central line of the body of the S-shaped pitot tube, and the perpendicular distance between the central line of the measuring head
