Zusammenfassung:The invention discloses a device and a method for measuring the gas content in oil. The device is provided with a degassing chamber and a comparison chamber which have the same volume, an oil sample is quantitatively conveyed to the degassing chamber or the comparison chamber through a quantitative unit, and the device is provided with a gas volume which is communicated with the comparison chamber, can compensate gas for the comparison chamber and can measure the compensated gas volume; the gas content in the oil is measured by using the volume of air required to be supplemented after the same amount of oil sample is degassed, and measurement is simple and easy to operate. The vacuum degree of the device can be monitored in real time through the electrode glow color of the high-voltage generator, it is guaranteed that the whole degassing process is carried out below 10 Pa, measurement accuracy is improved, an expensive absolute pressure sensor is not needed, and the cost is effectively reduced. Moreover, the
