1、通过减压和稳压,在线做
2、有种东西叫氧气袋。。
在线测定的装置牌子是什么呢??精度能达到多少呢???网上有这种装置!
Hydrogen analyzer / in-line / explosion-proof / process
HY-OPTIMA™ 2740
CharacteristicsGas type: hydrogen Other characteristics: in-line Protection level: explosion-proof
DescriptionHY-OPTIMA™ 2740 Explosion Proof In-line Area Hydrogen Analyzer (% H2S & CO)
H2scan’s Series 2700 real-time hydrogen specific process analyzers are designed for ease of use, interface flexibility and true process control. The HY-OPTIMA™ 2740 is a solid-state sensor configured to operate in background gas streams having carbon monoxide, concentrations up to 20% by volume, hydrogen sulfide concentrations up to 10% by volume, up to 95% relative humidity, and temperatures up to 65oC. The HY-OPTIMA™ 2740 is ideal for hydrogen production and petrochemical applications where real-time measurements of hydrogen can increase process plant efficiencies, improve diagnostics and enhance maintenance management translating into higher profitability.
