PURPOSE: A pyrolysis tube carburization measuring device and method are provided to precisely measure carburization by finding the moment when a rotary angle of a bar is zero. CONSTITUTION: A pyrolysis tube carburization measuring device comprises a bar(100). Magnetic force is added to right or left sides of a pivot point(130) and the carburization agent of the pyrolysis tube. The bar rotates rotation point rotates around a rotary point by the magnetic force difference which applied to left and right side. An electromagnet(200) is located on the upper and lower parts. A power supply unit(300) supplies electricity to the electromagnet. A rotation sensor(400) measures the rotation angle of a bar. A feedback controller(500) controls the magnetic force intensity according to the measurement result of the rotation sensor.
