自从50年代乔舒亚·西格尔开发出第一个可供商业用的催化元件以来,气体传感器市场已发展到年销售额数亿英镑的规模(最近的估计是,西欧和美国各为1亿英镑,世界其它地区约为3000万英镑)。70年代以来,在这一领域,电气化学式气体传感器一直占据主要地位,约占全球气体传感器市场25%份额。 Since the 1950s when Joshua Sigle developed the first commercially available catalytic element, the gas sensor market has grown to a scale of several hundred million pounds in annual sales (the most recent estimate is that Western Europe and the United States each have 1 Billion pounds, the rest of the world is about 30 million pounds). Since the 1970s, electrochemical gas sensors have occupied a major position in this field, accounting for about 25% of the global gas sensor market.
