The utility model discloses a pretreatment device for measuring hydrogen content in hydrogen chloride gas, which comprises a shell, flow meters, a dryer, an absorption bottle filled with saturated sodium chloride, a circuit board and an LED (light-emitting diode) screen, a data calculation unit is arranged on the circuit board, the flow meters comprise a first electronic flow meter and a second electronic flow meter, the absorption bottles comprise the first absorption bottle and the second absorption bottle, and the two electronic flow meters are electrically connected with the data calculation unit. According to the pretreatment device disclosed by the utility model, the hydrogen chloride gas with any concentration can be measured under the condition that a detection result is not influenced by pretreating the high-corrosion hydrogen chloride gas and calculating a result by utilizing a proportionality coefficient, so that the damage of the gas to a chromatographic instrument is avoided; meanwhile, as an ind
