The SM-3 mercury analyzer measures continuously the elemental, bound and ionic mercury in stack fluegas. The operating principle of the SM-3 is based on a completely new technique: mercury compounds cracking and the reduction of ionic mercury contained in stack gas is performed applying the thermocatalytic method. Wet chemical sample gas treatment using reagents and bubblers is avoided. Maintenance and servicing of the SM-3 are therefore extremely easy.

Technically identical to the SM-4, this device is ideal for mercury determination at varying sites. The SM-4 Mobile by Mercury Instruments has been developed on the basis of the well proven SM-4 mercury 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.

Beneficiary of over 20 years of experience in mercury measurement, the new SM-5 CEMS Hg analyzer is designed to provide extremely accurate and reliable continuous measurements of very low concentrations of Hg in flue gas emissions. The SM-5 features short response times, dynamic ranges and stable measurement under all circumstances.
