复合气体检测仪报警值设定标准
相信大家都知道,复合气体检测仪可以针对多种气体浓度进行检测分析,当检测气体浓度处于安全值会记录不同时段的检测数据,当某种气体超出设定值会发出声光报警,可以通过数据面板清晰看出哪种气体浓度超标并采取相应的措施,避免更大事故的发生。虽然,复合气体检测仪的用处很大,但是在使用的过程中,还是有很多朋友对于复合气体检测仪报警值设定标准都不太了解。那么您知道复合气体检测仪报警值设定标准是多少吗?下面逸云天小编为您介绍:

复合气体检测仪报警浓度值:

复合气体检测仪报警参数标准应当符合相应的国标规定,并且一般都是要有一、二级报警值的相关要求。根据国标《GBT 50493-2019》中对于可燃气体和有毒气体检测报警设计标准的相关规定,复合气体检测仪的报警值设定应符合以下条件:
1、可燃气体的一级报警设定值应小于或等于25%LEL。
2、可燃气体的二级报警设定值应小于或等于50%LEL。
3、有毒气体的一级报警设定值应小于或等于100%OEL,有毒气体的二级报警设定值应小于或等于200%OEL。当现有探测器的测量范围不能满足测量要求时,有毒气体的一级报警设定值不得超过5%IDLH,有毒气体的二级报警设定值不得超过10%IDLH。
4、环境氧气的过氧报警设定值宜为23.5%VOL,环境欠氧报警设定值宜为19.5%VOL。
5、线型可燃气体测量一级报警设定值应为1LEL·m;二级报警设定值应为2LEL·m。
综上所述,就是复合气体检测仪报警值设定标准,仅供大家参考。大家如果想要了解更多常见气体检测报警仪器的报警浓度值,欢迎来电咨询逸云天。
