| 摘 要： | 环境粉尘浓度的测定一般使用滤膜称重方法测得,该方法费时费力,且不能得到瞬时粉尘浓度的变化。由于光散射式数字式粉尘测试仪性能稳定、灵敏度高,测量方便而广泛的应用于各类测尘应用。文中介绍了光散射式数字粉尘测试仪各项指标的具体标定方法,并结合实际应用,总结了使用过程中应注意的事项。

| Abstract: | Weighing filtration membrane is often used to get the dust concentration of environment.However,this method is discommodious and can not get the instantaneous transformation of dust concentration.Since the digital light scattering dust test instrument is quite steady,sensitive and convenient in measurement,it can be used in many kinds of dust testing applications.This paper introduced the calibration of digital light scattering dust test instrument and mentioned some key points in measurement process. |
