氢气检测仪如何设置量程?
氢气是一种易燃易爆易挥发的气体,它在空气中浓度达到40000ppm~750000ppm就会爆炸。但是,氢气做为重要的工业气体和特种气体,在石油化工、电子工业、冶金工业、食品加工、浮法玻璃等方面有着广泛的应用。在使用过程中,需要谨慎操作,以免氢气泄露。微量的氢气泄露,人们是很难发现的,所以需要借助氢气检测仪进行设置量程来监控作业环境中是否存在氢气,通过检测数据来了解氢气是否泄露,从而杜绝了氢气泄露爆炸火灾事故的发生。那么氢气检测仪如何设置量程呢?下面逸云天小编为您介绍:

氢气检测仪设置量程的方法:
以ppm为单位:0~500ppm、0~1000ppm、0~2000ppm、0~5000ppm。
以Vol为单位:0~20%Vol、0~50%Vol、0~100%Vol、0~100%LEL。
目前常规氢气检测仪可选量程有100、500、1000、5000、10000、50000等量程范围,所以关于氢气检测仪的量程设置需要根据氢气环境的需求来设置,如在一些高温易燃环境,则需要选择大量程的范围,如对于比较微小低温可燃场所,则建议可设置低量程的范围设置。
因此,在工业生产中一般根据需要选择合适的检测范围,并选择对应量程范围的氢气检测仪,否则,当测量的气体浓度范围超出气体传感器的量程范围会影响气体传感器的使用寿命,并导致测量数据的不准确。如果大家对于氢气检测仪的量程设置并不太了解,也可以来电咨询逸云天,我们将会根据您的具体应用场所来推荐合适的氢气检测仪量程数值。
