Monitoramento automático de mercúrio em chaminés
SM-3
O SM-3 mede continuamente mercúrio elementar, ligado e iônico em gases de combustão.
O princípio de funcionamento do SM-3 baseia-se numa técnica completamente nova: o craqueamento dos compostos de mercúrio e a redução do mercúrio iónico contido nos gases de escape são realizados termocataliticamente.
O tratamento químico úmido do gás de amostra com reagentes e borbulhadores é evitado. Portanto, a manutenção e reparo do SM-3 são extremamente simples.
Exemplo de uso:
Também pode ser usado para aplicações móveis.
