FIELD: measurement equipment.
SUBSTANCE: electrochemical gas sensor contains electrolyte, including at least one ion liquid and at least one working electrode. Potential of the working electrode is mainly maintained as permanent. The ion liquid contains an additive part, including at least one organic additive in the amount from 0.05 to 5.0 wt %. The invention also relates to a device of an electromechanical gas sensor and its application for detection/measurement of gases chosen from a group including NH3, SO2, H2S, H2, HCl, HCN and mixed gases.
EFFECT: invention makes it possible to produce an electromechanical gas sensor with higher sensitivity, selectivity, which is achieved due to the additive.
