PROBLEM TO BE SOLVED: To provide a highly reliable monitor for dissolved gas in oil capable of enhancing an extraction rate of the dissolved gas, and capable of reducing dispersion of the extraction rate, by preventing a measurement-finished sample oil from being mixed with a newly collected sample oil, and by preventing a volume of a gas extraction space in a gas extraction chamber from being fluctuated. SOLUTION: In this monitor for the dissolved gas in the oil provided with a gas extraction part 4, a gas measuring part 16 and a control part 23, the gas extraction chamber 6 is pressurized by an air pump 18, when replacing an insulating oil in an oil sampling chamber 5. The gas extraction chamber 6 is communicated with the oil sampling chamber 5 to make pressures of the both chambers equal by a bypass pipe line 15, when extracting the dissolved gas into the gas extraction chamber 6.
