FIELD: investigating or analyzing materials.
SUBSTANCE: device for testing filtering materials comprises presser-tight vessel for fluid that receives mixer with a drive arranged along its axis. The outlet branch pipe underlies the vessel and has tree-way cock connected with the flow-type clamp for receiving the flat specimen. The device also has source of compressed gas connected with the top section of the vessel through the valve gate with the electric actuator whose supplying line is provided with the pressure gauge. The pressure-tight vessel filled with fluid is provided with the temperature sensor, which is provided with heat insulation and can be heated, four-way cock mounted downstream of the clamp, flow-type chamber for testing solid specimens, by-pass, and control unit. The pressure gauge and temperature sensor are connected with the inputs of the control unit. The outputs of the control unit are connected with the control inputs of the three-way and four-way cocks, mixer actuator, and heater of pressure-tight vessel. The outlet branch pipe of the vessel is additionally connected with the chamber for testing solid specimens through the special passage in the three-way cock, by-pass, and four-way cock.
EFFECT: enhanced efficiency of testing.
