Summary:Disclosed are an apparatus and a method for measuring oxygen. The apparatus for measuring oxygen according to an embodiment of the present invention includes: an indicator accommodating portion provided in a sealed space and accommodating an indicator whose color changes according to ionization in response to oxygen present in the sealed space; a voltage measuring portion having an electrode pair contacting the indicator and measuring a magnitude of a voltage generated between the electrode pair as the indicator is ionized; and a microcontroller for calculating the concentration of oxygen present in the sealed space from the measured magnitude of the voltage, thereby capable of visually confirming the concentration of oxygen present in the sealed space. 산소 측정 장치 및 방법이 개시된다. 본 발명의 일 실시예에 따른 산소 측정 장치는 밀폐된 공간에 구비되며, 상기 밀폐된 공간에 존재하는 산소와 반응하여 이온화됨에 따라 색깔이 변하는 지시약이 수용되는 지시약 수용부; 상기 지시약에 접촉되는 전극쌍을 구비하며, 상기 지시약이 이온화됨에 따라 상기 전극쌍 사이에 발생되는 전압의 크기를 측정하는 전압 측정부; 및 측정된 상기 전압의 크기로부터 상기 밀폐된 공간에 존재하는 산소의 농도를 산출하는 마이크로 컨트롤러를 포함한다.
