氧氮氢分析仪的使用注意事项:1、氧氮氢分析仪在初次启用前,应该对连接点、焊点、阀门等进行检漏,以确保空气中的氧不会反渗进入管道及仪器内部,造成测量数值偏高。2、再次使用仪器前,要进行管道系统净化,将漏入的空气除干净,同时确保连接取样管路时没有漏入空气。3、样气中氧含量的变化会受管道材质及表面粗糙度影响,因此一般连接管路选用铜管或抛光过的不锈钢管,而不用塑料管、橡胶管等。4、微量元素分析时,要避免各种管件、阀门、表头等死角对样气造成污染,因此必须尽可能的简化气路系统,连接件死角要小,以防止溶解氧逸出造成污染,使用水封、油封及腊封等设备,才能较好的确保数据的。分析仪,就选上海禹重实业有限公司,有需求可以来电咨询!慈溪H836分析仪
