SM-4 Mobile Mercury Stack Gas Monitor ENVEA - 1

Mercury Instruments The Mercury Stack Gas Monitor SM-4 mobile is meant for automatic monitoring of total mercury emissions (CEM) at different sites. The SM-4 mobile was developed on the basis of the well proven Mercury Stack Gas Monitor SM-4. Its measurement principle and technique, its thermocatalytic reactor, the detector and the sample probe are identical with those of the stationary SM-4. Designed for accurate and reliable measurement of very low mercury Automatic calibration for elementary and ionic Hg concentrations in flue gases within complex Automatic quality control (QAL3) during operation matrices (S°2, nox, hc|, etc.) SPECIFIC FEATURES ■ Modular construction: easy to transport ■ Qickly dismounted and reassembled ■ Sample dilution directly at the probe: eliminates interference with virtually any sample matrix ■ Maintenance free low temperature converter directly at stack: no transport of ionic mercury thus minimizing mercury adsorption ■ Detects total mercury (elemental, ionic and bound mercury) i Extremely wide range of measurement: 0,05 bis 1000 pg/m3 i Heated particle filter with automatic cleansing Length of sample line up to 100 meters APPLICATIONS Coal fired power plants Waste incineration plants Sewage sludge incineration plants Cement kilns Method 30A applications Testing of stationary CEMs Optimizing of mercury control technologies Recording of Hg-emission situations as well as determination of the efficency of Hg-reduction techniques
