PGC EnCal 3000

L’ EnCal 3000 è un gascromatografo progettato specialmente per la misura fiscale  del gas naturale. Usa componenti cromatografici basati sulla più recente tecnologia dei sistemi microelettromeccanici (MEMS). Questo permette di avere ottimi risultati di ripetibilità e di analisi accurata. L’analizzatore compatto contiene l’hardware analitico, selezione del canale di misura e tutta l’ elettronica necessaria per lavorare in autonomia.
