WLD-5C(B)微电脑激光粉尘仪

shoe
1.        ★★设计了可更换的粒子切割器,实现了PM10PM5 PM2. 5 PM1 TSP多种粒子分离切割器兼容。
2.        设计了在线滤膜采样器,实现了连续监测粉尘浓度与滤膜采样兼容,可以分析所收集到颗粒物的成份以及求出该场所的质量浓度转换系数K值。
3.        采用激光光源,质量浓度转换系数不受颗粒物颜色的影响。
4.        采用大屏幕液晶汉字显示,实现了汉字菜单提示。
5.        设计了恒流控制器,确保采样流量恒定,切割曲线的正确。
6.        具有内装光学标准散板,确保仪器高稳定性。
7.        具有特别的保护气幕,避免了粉尘对仪器核心部件光学系统的污染,确保仪器高可靠性
8.        通过计算机软件实现仪器零点自动调节,提高了仪器测量精度,方便了用户使用。
9.        仪器设计了定时采样机构,可根据设定时间定时采样,定时启动及关闭,所得数据可通过微型打印机记录或导入PC机进行数据处理,而使仪器适合于大气环境可吸入颗粒物连续监测。
10.     仪器可设定粉尘浓度超标报警阈值,粉尘超标时自动声光报警,或将信号传输到控制中心进行监控。
11.     仪器设计了模拟量输出接口,对空气净化器进行评价?#20445;?#21487;绘制出净化效率评价曲线。
12.   除设有适合室内公共场所粉尘监测的?#35805;?#27979;量模式和适合大气环境监测的定时采样模式外,新增加了劳动卫生模式,在此模式下,根据工业企业卫生标准(GBZ1-2002)和工作场所有害因素接触限值标准(GBZ2-2002),计算出时间加权平均值(TWA)以及短时间接触容许浓度(STEL)。
