Abstract: This article discusses some considerations for verifying and calibrating gas detection alarms and gas analyzers from the perspectives of determining technical specifications, selecting gas reference materials, selecting zero gas, flow effects, instrument adjustments, and selecting pressure relief valves and pipelines. It further discusses safety considerations for verification, and hopes to provide assistance for related verification work.
Keywords: gas detection alarm; gas analyzer; verification; calibration
0引言
氣體檢測(cè)報(bào)警器是用于檢測(cè)某種氣體濃度,當(dāng)氣體濃度達(dá)到一定數(shù)值后發(fā)出報(bào)警提示的儀器。(剩余4016字)
