Explosion-proof process analyzer is made to measure mass content of mercaptans based on ethyl mercaptan concentration in gaseous media, including natural gas, with further calculation and scoring odor intensity and data transmission to external devices. Odor intensity is calculated proportionate to mercaptan concentration. Analyzer may be used in gas metering systems, within state metrological control and supervision distribution, including for natural gas quality control. Its principle of operation is based on determination of mercaptan medium concentration in natural gas using electrochemical detector (ECD) and separating the interfering component, which is hydrogen sulfide.

The mercury analyzer is designed for continuous measurements of the mass concentration of mercury vapor in natural and process gases. Advantage: Determination of atomic mercury by atomic absorption
