内蒙喀喇沁医院安装天鹰测温门

时间:2020-06-21|作者:天鹰安防

      感谢内蒙喀喇沁医院安装天鹰测温门,用于辐射进出医院的温度筛查工作。19年11月突然接到内蒙经销商电话,内蒙有-鼠-疫,具备一定的传染性,且会出现发热症状,一天时间里来自内蒙的电话暴增,都是需求天鹰测温安检门的。

      两周时间里内蒙各地医院陆续安装了我司测温安检门,感谢内蒙喀喇沁医院院安装了我司这款设备。

      医-院-进出的各种医病患者很多,其中也包括流行性病源,以及流行感冒等,如何控制这些扩散,如果每个人进医院的人都要亲自量体温,会不会造成很大的工作量,于是我司针对出现在的情况,为医院等特殊场所量身设计了这一款智能测温安检门,即可监测温度异常,又能检查进入医院的人员有没有携带危险器具,是一举两得的选择。

    一、功能特点如下:有机将红外测温与金属安检融合,通过金属安检门前,先进行红外人体测温,真人发音提示,提示体温异常,有效防止规模性疾病传染;, 豪华LCD显示,中英文双语菜单;面板数字键操作; 红外线遥控操作;电脑远程联网操作(定制)。

   操作方式:面板数字键操作;红外线遥控操作;电脑远程联网操作(定制);豪华LCD显示,中、英文菜单;

    探测区域:根据人体基本结构将探测门划分为多个相互重叠的探测区域,采用网状探测方式和单一频率激励技术,消除探测区域内的弱区和盲区,灵敏度更高,性能更稳定。

      提示方式:声光提示,音调快慢可区分金属物大小,多种报警音量模式适用于不同场合的选择,通过门柱左右超亮LED报警灯可准确显示人体相应高度藏匿的违禁物品。测温报警:真人发音报警,提示体温异常;

     区域灵敏度:比较高灵敏度可以探测到一元硬币大小的金属含量物体,可在0-255级灵敏度之间自行调节、可根据探测要求把各区位调节器调到适当的灵敏度。
