KH-3000-01A 花粉监测仪

光散射法监测空气中花粉数量

KH-3000-01A 通过漏砂柱有效收集花粉颗粒,是一款通过前向和侧向的光散射原理花粉数量的粒子计数器。

KH-3000-01A 与传统的花粉数测定方法(如 Cascade、Burkard 等)相比,极大地帮助了研究人员节省时间,减少了花粉数量测量的工作量。通过前向和侧向的光散射原理,KH-3000-01 能高效可靠识别花粉和其他颗粒(例如纤维粉尘)。

测量原理

Operating Principle

通过 RS-232 电缆连接打印机或个人电脑来收集观测数据。在远程模式下,可以通过电脑发出的命令来控制 KH-3000-01A,并且可以方便地将观测数据保存在 PC 机上。
