FIELD: technologies for controlling hazardous admixtures in atmosphere. ^ SUBSTANCE: device integrates on one side of crystal a heater of special shape, concurrently used as thermal resistance and two gas-sensitive elements, one of which is covered by gas-impenetrable layer and serves as a comparison element in measurements. To provide for even distribution of temperature along crystal heater in form of H letter is positioned not only along perimeter but also in the center of crystal. ^ EFFECT: broader functional capabilities, higher efficiency. ^ 2 dwg |
