The double diaphragm system increases safety when sampling expensive or extremely hazardous gases. Should the primary diaphragm fail, the other diaphragm keeps the sample flow intact. The 1/8" NPT port connection allows the user to add a leak detection system and alarm. The detection system monitors the diaphragm for failure analysis and assures system integrity until maintenance can be performed.
