description Provided is a chalcogen gas monitoring device. The chalcogen gas monitoring device includes a reaction unit which varies in resistance due to reaction occurring by contact between chalcogen gas and a metal foil, a measurement unit measuring a resistance value according to the variation in resistance, a calculation unit measuring at least one of whether the chalcogen gas exists and a concentration of the chalcogen gas according to the resistance value, and a display unit outputting the measured results; wherein the metal foil is replaced according to results obtained by the reaction between the metal foil and the chalcogen gas.
