PROBLEM TO BE SOLVED: To allow detection of an air leaking point of an air tube when an air leak is recognized in the air tube by performing an operation test of a differential distribution type heat sensor of an air tube type. SOLUTION: An inspection set comprises: a gas feeder (1) feeding a reactive gas to the air tube of the heat sensor; a gas detector (2) detecting the reactive gas; and an air injection pump (3) replacing the reactive gas in the air tube with air. The gas feeder (1) is equipped with: a gas cylinder (17); a gas injection tube (10) into which the reactive gas is injected; a going path tube (12) and a return path tube (13) connected to the gas injection tube (10) and including valves (120, 130), respectively; a tube connector (14) connecting an air tube going path part (461) disconnected from the heat sensor to the going path tube (12) and connecting an air tube return path part (462) to the return path tube (13); and a pressure gauge (15) measuring a gas pressure of the return path tube (13).
