Constant-temperature determinator for density of powdery material

The utility model provides a powder material density constant-temperature tester, which relates to the field of powder material density detection and comprises a constant-temperature water tank with a support plate and a Lee bottle placed on the support plate on the inner side of the constant-temperature water tank, cover plates are arranged on the two sides of the Lee bottle, and connecting rods are arranged on the side surfaces of the two cover plates. By placing the Lee's bottle between the two connecting blocks and pushing the connecting rods, the connecting rods drive the cover plate to be close to the Lee's bottle, the cover plate drives the gasket to be attached to the surface of the bottom end of the Lee's bottle, the Lee's bottle is fixed up and down, and it is avoided that when a water source exists on the inner side of the constant-temperature water tank, the gasket is attached to the surface of the bottom end of the Lee's bottle. The detection of the density of the powder on the inner side of the
