PURPOSE: A measuring device of the gas of sediment in closed space is provided to safely measure the gas generated in the closed space externally. CONSTITUTION: A measuring device of the gas of sediment in closed space (100) comprises: a gas guide (120), which of the one end is inserted in the sediment, inducing the gas generated from the sediment (162) to the exterior of the closed space (160); an air injection unit (150), which is connected to the one and of the gas guide, injecting air to the sediment and generating the gas; and a gas measuring unit (140), which is connected to the other end of the gas guide, measuring the generated gas. An inserting member (122) which is inserted to the sediment is and arrange in the one end of the gas guide. An air injecting pipe connected to the inserting member in the exterior of the gas guide and inserted in the sediment so that injecting the air. |
