摘要： PROBLEM TO BE SOLVED: To provide a dissolved gas concentration measuring method and device, capable of accurately measuring the concentration of gas dissolved in liquid (solution) in a short time.
SOLUTION: A liquid flow of a gas-dissolved liquid 10 is made to act in advance on a gas permeation film 7 of a dissolved gas sensor 1, and is vaporized and separated. Measurement for detecting the gas concentration by a gas detector 3 is performed until gas partial pressure becomes a balanced state, and reference data is acquired to be held in a pair with measurement elapsed time. In the measurement of the gas concentration, the measuring object liquid 10 is quickened to a flow speed equal to the liquid flow when acquiring the reference data by a water feed pump, and is made to act on the gas permeation film of the dissolved gas sensor. The specific concentration is determined from measured data and the reference data, and compared in the middle of the measurement for detecting the gas concentration by the gas detector. When both specific concentrations are matched, the dissolved gas concentration in the balanced state is estimated based on the measured data.
