The utility model discloses an ultralow emission gas detection device which comprises a sampler and a gas detection device which are connected through a sampling pipe, a sampling head is arranged at the front end of the sampler, and a telescopic mechanism is arranged at the rear end of the sampler; a handle is arranged at the rear end of the telescopic mechanism; and a sampling mechanism is arranged in the sampler. The ceramic layer is arranged in the sampler, and the inner wall of the ceramic layer is smooth, resistant to high temperature and corrosion and not prone to adsorbing gas components; by arranging a flow baffle, when the sampling head sucks the gas and the gas passes through the flow baffle, the gas below the central line of the gas channel is blocked, the flow direction of the gas is changed, the gas near the detection end of the gas detection probe is convected, the gas flow speed is reduced, and detection is facilitated; and finally, through the design of a telescopic mechanism, the sampler can
