这是一种小型的、用电化学法测定气体的仪器(亦可称小型氩气测定仪)。这是美国海岸检查站提供的标准,用来检定不同气体及蒸汽易燃倾向的仪器,必须能达到测痕量杂质的能力(即ppm百万分之几),可以测定烃、取代烃(如气体中的氢、一氧化碳、硫化氢、二氧化氮)。现在这个仪器可以作为定量监察器,对化学 This is a small, electrochemical gas analyzer (also known as a small argon gas analyzer). This is a standard provided by the U.S. Coast Guard to test the suitability of different gases and vapors for flammability to measure trace impurities (ppm parts per million), to measure hydrocarbons, to replace hydrocarbons Gas in hydrogen, carbon monoxide, hydrogen sulfide, nitrogen dioxide). Now this instrument can serve as a quantitative monitor for chemistry
