Sistema de medição a laser NH₃ (TDLS)
A série LGD 2M é baseada em uma medição no infravermelho próximo da absorção do gás alvo. Os sistemas são módulos OEM independentes e prontos para uso que utilizam uma configuração extrativa da amostra a ser analisada.
ENVEA oferece este sistema de medição de NH3 compacto e montável em rack (rack 3U) integrado em suas bancadas de análise prontas para uso para medições contínuas de gases do motor.
Seu princípio de medição é baseado na detecção de gás usando espectrometria de laser de diodo sintonizável (TDLS), que oferece inúmeras vantagens e valor excepcional para o cliente.
