PURPOSE: A device for measuring dissolved hydrogen in the boiler water is provided to remove the need for electrolyte to be frequently replaced and to raise the reliability of a dissolved-hydrogen meter. CONSTITUTION: A device for measuring dissolved hydrogen in the boiler water comprises a gas extraction unit(4), a three-electrode hydrogen sensor(7) and a status lamp(10). The gas extraction unit introduces the cooled boiler-water to the device and extracts only dissolved hydrogen from the boiler water using a fluorinated polymerized gas extracting film. The three-electrode hydrogen sensor detects the extracted dissolved-hydrogen. The status lamp receives a signal for the detected dissolved-hydrogen, converts and indicates it to a concentration. The status lamp indicates statuses(normal, less abnormal, much abnormal) depending on the concentration. The three-electrode hydrogen sensor comprises a hydrogen-gas inlet and an air inlet.
