This one gas is used as the carrier, the flushing gas and\/or the purging gas.<br \/>\nThis gas can also serve to purge and clean all the valves.<br \/>\nThe housing does not require flushing gas: no contamination of the gas circuit is possible before detection as the input connection is located directly on the cell of the DID detector.<br \/>\nThe power setting of the high frequency oscillator allows for the adjustment of the detector sensitivity, which can reach 0.1 ppb (parts per billion).<br \/>\nThe detection limit and any background noise are directly related to the quality of the carrier gas, so the use of ultra purity (UHP) Helium as the carrier gas is highly recommended.<\/p>\n<h6>Applications<\/h6>\n<ul>\n<li>Air separation plants<\/li>\n<li>Cryogenic truck loading station<\/li>\n<li>Specialty gas laboratories<\/li>\n<li>Process control<\/li>\n<li>Steel industry<\/li>\n<\/ul>\n<p>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column css=&#8221;.vc_custom_1513937394488{margin-top: 10px !important;}&#8221;][vc_btn title=&#8221;DATA SHEET DID 500&#8243; style=&#8221;custom&#8221; custom_background=&#8221;#4e8ec3&#8243; custom_text=&#8221;#ffffff&#8221; align=&#8221;left&#8221; link=&#8221;url:http%3A%2F%2Fwww.aptsrl.com%2Fanalizzatori%2Fwp-content%2Fuploads%2F2018%2F01%2FDID-500.pdf||target:%20_blank|&#8221;][\/vc_column][\/vc_row][vc_row][vc_column css=&#8221;.vc_custom_1513937394488{margin-top: 10px !important;}&#8221;][vc_btn title=&#8221;DATA SHEET DID 500 Ar&#8221; style=&#8221;custom&#8221; custom_background=&#8221;#4e8ec3&#8243; custom_text=&#8221;#ffffff&#8221; align=&#8221;left&#8221; link=&#8221;url:http%3A%2F%2Fwww.aptsrl.com%2Fanalizzatori%2Fwp-content%2Fuploads%2F2018%2F01%2FDID-500Ar.pdf||target:%20_blank|&#8221;][\/vc_column][\/vc_row]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column][vc_column_text] The DID500 is an analytical system that measures H2 , Ne, O2+Ar, N2 , Kr, CH4 , CO, CO2 and Xe, in Helium, Argon, Hydrogen, Nitrogen and Oxygen.
