  • 具有可更换粒子切割器PM10、PM5、PM2.5及TSP供选择;
  • 直读粉尘质量浓度(mg/m3),1分钟出结果;
    4、 大屏幕液晶显示器,汉字菜单提示;
  • 检测灵敏度:LD-5C(L) 0.01mg/m3; LD-5C(H) 0.001mg/m3。
  • 重复性误差:±2%
  • 测量精度: ±10%
  • 测量范围: LD-5C(L) 0.01~100 mg/m3; LD-5C(H) 0.001~10 mg/m3。
  • 测定时间:标准时间为1分钟,设有0.1分及手动档(可任意设定采样时间)。
  • 具有公共场所监测模式、大气环境监测模式以及劳动卫生模式。可计算出时间加权平均值(TWA)和短时间接触允许浓度(STEL) 等。
  • 存 贮:可循环存储99组数据。
  • 定时采样:可设定测量时间(1~9999)秒,关机时间(0~9999)秒, 预热时间(0~10)秒及采样次数(1~9999)次。
