<div style="margin: 0cm 0cm 12pt; line-height: 18.75pt" align="left">当氮气浓度低于1号下限设定值时(假如是99.96%),报警指示灯亮，同时有报警声响，1号报警输出开关启动(可当预警提示,或启动相应的设备).. 当氮气浓度继续下降低于2号下限设定值时(假如是99.93%), 2号报警输出开关启动.(可根椐需要启动相应的控制设备)..这样更有利于产品质量的生产管理.如果只用1路设定值,那就把2号下限控制数码拨至90.00即可.2种仪表都带有4～20mA信号输出可与记录仪连接。<br />
本仪器适用于变压吸附制氮机，空分设备，以及氮氧混合气中的氮气浓度分析、监测和控制。</div>
