The invention discloses a dual-purpose testing device for a rheometer and a tribometer. The dual-purpose testing device comprises a device body which is formed by a rheometer detection braking tank, an emergency stopping button, a starting button, a touch screen controller, a torque sensor, a connecting device, a cross rotor, a stainless steel testing bucket, a support base, a lower instrument protecting cover, a stainless steel moving guide rail, a stainless steel mounting lining plate, a testing bucket positioning lining support, a stainless steel testing bucket handle, portable Foma wheel support seats and portable Foma wheels. The rheometer detection braking tank is arranged at the top end of the device body, the touch screen controller is arranged on one side of the rheometer detection braking tank, and the emergency stopping button is arranged on one side of the touch screen controller, so that the functions of the rheometer can be realized; by utilizing a cross, the dynamic yield stress and viscosity of pump concrete can be detected; secondly, the depth of a rotor penetrating into the concrete can be accurately controlled by the testing device; and by utilizing a cone-shapedrotor, the resistance applied by the concrete to the rotor can be accurately tested.
