光学尘埃粒子计数器是利用尘埃粒子在强光照射下产生散射光,通过检测散射光强度设计而成,仪器接收灵敏度的稳定性是保证测量准确度的关键。提出了一种尘埃粒子计数器实现自动校正的方法,使仪器始终处于定标时的接收灵敏度。
Optical dust particle counter is the use of dust particles in the strong light irradiation to produce scattered light through the detection of scattered light intensity designed to receive the stability of the receiver sensitivity is to ensure measurement accuracy of the key. A method of automatic correction of dust particle counter is proposed, which makes the instrument always receive the calibration sensitivity.
