摘要： A laser type gas analyzer for ships, with a structure in which optical axis deviation hardly occurs, accurately analyzes a gas concentration of measurement target gas contained with a low concentration in exhaust gas and over a long period of time, by performing analysis only in a designated sea area without analysis in a general sea area to eliminate an influence of the exhaust gas in the general sea area. A laser type gas analyzer 1 for a ship is configured such that a cylindrical gas cell 20 is disposed outside a duct 100 and an opening portion 41 of a duct side gas introduction part 40 is provided in a flow path of the duct 100 through which a measurement target gas flows so that a control unit 80 opens an introduction side valve 60 and a lead-out side valve 70 to introduce the exhaust gas into the gas cell 20 only when the exhaust gas containing the measurement target gas with a low concentration flows such as in a designated sea area.
