style="font-family:宋体"> 粒子计数器是国家规定的计量器具，在使用一段时间后，其光学系统及检测系统都会发生变化，如光源老化、发光效率降低或聚焦错位、透镜被污染，从而使整机的转换灵敏度变化。激光尘埃粒子计数器采用气泵，噪声更低，电磁干扰更小；供电采用大容量锂电池与直流电源适配器转换供电，外形设计大气简洁，体积小，重量轻,使用方便，全不锈外壳更能符合GMP的要求。广泛应用于电子、光学、化学、食品、化妆品、医药卫生、生物制品、航空航天等部门。</span></span></p><p>

style="font-size:10.5000pt"><span style="font-family:宋体">激光尘埃粒子计数器使用条件：</span></span></p><p><span style="font-size:10.5000pt"><span style="font-family:宋体">1、洁净室环境，周围无强磁场干扰；请勿长时间在大气中作业，防止传感器污染，</span></span></p><p><span style="font-size:10.5000pt"><span style="font-family:宋体">2、电源：标配电源充电器。</span></span></p><p><span style="font-size:10.5000pt"><span style="font-family:宋体">所谓等动力采样就是在检测时，粒子的计数器的采样管的入口方向与被采样的单向气流方向相一致，而且空气进入取样管入口的平均速度与该位置单向气流的平均速度相同。</span></span></p><p><span style="font-size:10.5000pt"><span style="font-family:宋体">因为对净化车间的检测我们主要关心两种粒径，即0.5um和5um。非等动力采样对于≤0.5um的粒子影响不大。如果取样空气用于计算大于或等于0.5um的粒径浓度，如果这些粒子不受非等动力条件的影响，则计算结果也不受影响。因此，净化车间区域内的非等动力取样仅对大于或等于0.5um粒子才有意义。</span></span></p> </div> </div>
