Abstract
A device for measuring a gas dissolved in an oil comprising a sample container for containing a sample oil, an air bubble generator for extracting the gas dissolved in the oil, a gas container for containing the gas, a gas sensor for detecting the gas charged in the gas container, gas measuring means for measuring a concentration of the gas in response to a signal dispatched from the gas sensor, and a pump for supplying air to the air bubble generator.
Claims20
A device for measuring a gas dissolved in an oil sample, comprising:
- a sample container for containing an oil sample;
- an air bubble discharging means, provided in said sample container, for extracting a measurement gas dissolved in said oil sample;
- a gas container for containing said measurement gas extracted by said air bubble discharging means;
- gas detecting means for detecting said measurement gas charged in said gas container;
