Automatischer Quecksilber-Monitor für Rauchgas


Der SM-3 misst kontinuierlich elementares, ionisches und gebundenes Quecksilber in Rauchgas. Das Probengas wird direkt am Kamin thermokatalytisch behandelt.

Das Funktionsprinzip des SM-3 basiert auf einer völlig neuen Technik, der Thermokatalyse: gebundenes Hg wird freigesetzt und ionisches Quecksilber wird zu elementarem Hg reduziert.

Nasschemische Probengasbehandlung mit Reagenzien und Gaswäschern wird vermieden. Die Wartung des SM-3 ist deshalb äußerst einfach.
