补充资料：林格曼烟尘浓度图
分子式：
CAS号：

性质：用比较法测定烟尘浓度时广泛使用的一种规格图。该图是由14cm×20cm，黑度不同的六小块图板组成，除全黑、全白外，其他四块是在白色背底上，涂上不同比例的黑色小格，使黑色小格占白色背色的百分比分别为20％，40％，60％，80％，由此把煤烟浓度相应地区别为6级，即0~5级。使用时将林格曼图板竖立在与观测者眼睛相同的高度上，然后在距离图板15m，距离烟囱40m处注视此板，与离烟囱口30～45cm处的烟尘浓度进行对比，即可得知烟尘浓度。使用时，观测者位置应与烟气流向成直角；不要面向太阳；烟气出口处的背景上不应有高大的树木和建筑物。级数烟气特点黑色小块占总面积/%烟尘量/(g/m3)0全白001微灰200.252灰400.703深灰601.204灰黑802.305全黑1004.0~5.0
