摘要（英）：

The invention provides a constant-temperature automatic control device of an oscillation instrument for the chromatographic test. The device comprises a microcontroller, a temperature sensor, an inputdevice, a display screen and a heating control circuit. The microprocessor is connected with the temperature sensor, the input device, the display screen and the heating control circuit, respectivelythrough data lines. The temperature measuring point of the temperature sensor is arranged in the oscillation instrument for the chromatographic test. The heating control circuit is electrically connected with a heater in the oscillation instrument for the chromatographic test. By adopting the oscillation instrument for the chromatographic test, the temperature in the oscillation instrument for the chromatographic test can be automatically, stably and rapidly adjusted. Therefore, the temperature in the oscillation instrument is kept constant to be the same as a given test temperature. The measuring accuracy of the content of the dissolved gas component in the insulating oil of the electrical equipment is improved.
