The SM-4 mobile by Mercury Instruments was developed on the basis of the well proven SM-4 Stack gas monitor. Its measurement principle and technique, its thermocatalytic reactor, the detector and the sample probe are identical with those of the stationary SM-4.
Due to its modular design, the SM-4 mobile can easily be transported, assembled and disassembled. It is the ideal solution for the determination of total vapor phase mercury emissions at varying sites.
