Patent number: 9863932Abstract: A gas measurement apparatus of the present invention includes a gas sensor and is capable of being in any one of an open state in which the gas sensor is connected to an outside air and a closed state in which the gas sensor is cut off from an outside air. The gas measurement apparatus includes: an acquisition unit; and a determination unit. The acquisition unit acquires a detection value of the gas sensor in the open state and a detection value of the gas sensor in the closed state. The determination unit compares the detection value of the gas sensor acquired in the open state and the detection value of the gas sensor acquired in the closed state to thereby determine the state of the gas sensor.Type: GrantFiled: September 16, 2015Date of Patent: January 9, 2018Assignee: TANITA CORPORATIONInventors: Ayumi Sano, Naotaka Minagawa, Miyuki Kodama, Yasuhiro Kasahara
