Laser-Gasdetektor NH₃ (TDLS)
Die LGD 2M-Serie basiert auf einer optischen Absorptionsmessung. Die Systeme sind in sich geschlossene OEM-Module, die eine Durchflusszelle für extraktive Messungen verwenden.
ENVEA bietet dieses rackbare und kompakte NH3-Messsystem (3U-Rack) an, das in seine schlüsselfertigen Analysebänke für kontinuierliche Motorgasmessungen integriert ist.
Sein Messprinzip basiert auf der Gasdetektion durch abstimmbare Diodenlaserspektrometrie (TDLS), die viele Vorteile und einen außergewöhnlichen Wert für den Kunden bietet.
