ABSTRACT:
Apparatus and method for measuring a dissolved gas in oil wherein air is blown into an oil sample through a bubble generator, bubbles are passed through the oil sample to extract dissolved gas therefrom, a resulting air-extracted gas mixture is contacted by a gas sensor for detecting and measuring the dissolved gas and the mixture is recirculated through the oil sample. Preferably, the air bubbles are within the range of 0.1 mm to 8.0 mm, and, also, the volume of the apparatus is selected so that the quantity of the gas to be measured is not more than 20% of the combined volume of the extraction vessel, the sensor chamber, and the connecting conduit.
