臭氧检测仪的检测原理有哪几种?
臭氧检测仪主要由低压紫外灯,光波过滤器、入射紫外光反射器、臭氧吸收池、样品光电传感器、采样光电传感器、输出显示、电路部件构成,它是目前在很多工业环境场合中,用于检测臭氧含量浓度的一种仪器。由于应用场合的不同,其检测原理也会有所不同。那么您知道臭氧检测仪的检测原理有哪几种吗?下面逸云天小编为您介绍:

臭氧检测仪的检测原理,主要有以下几种:
1、半导体原理
半导体原理是指用半导体器敏元件检测,当用臭氧检测仪检测臭氧时,半导体电阻变小(半导体N型元件),主要原因是元件中的载流子电子增多,显示的浓度与比例关系和半导体器敏元件型号有关。
2、电化学原理
电化学法是被测臭氧气体以扩散方式或泵吸方式和仪表接触,并发生反应。输出稳定的电信号。气体浓度值可以稳定地用数据显示在显示屏上,此方法检测臭氧简单方便,随拿随测。
3、紫外光法原理
臭氧检测仪采用紫外线吸收法的原理,用稳定的紫外灯光源产生紫外线,用光波过滤器过滤掉其它波长紫外光,只允许波长253.7nm通过。经过样品光电传感器,再经过臭氧吸收池后,到达采样光电传感器。通过样品光电传感器和采样光电传感器电信号比较,再经过数学模型的计算,就能得出臭氧浓度大小。
综上所述,我们可以看出,臭氧检测仪的检测原理主要有半导体原理、电化学原理、紫外光法原理三种,具体需要选择哪种原理时,就需要大家根据自身的实际情况以及需求来进行选择了。
