产品概述
YX-PM2.5颗粒物在线分析仪采用β射线法,具有较强的抗干扰能力,不受温度、压力、磁场等环境因素的影响,可连续自动测量环境空气中悬浮颗粒物的浓度。分析仪通过外接不同的切割头,可测量各种颗粒物的浓度,如:TSP、PM10、PM2.5、PM1.0等。广泛应用于气象、海洋、机场、农业、国防、航天、科研、环境空气监测、室内环境监测、环境评价、职业病健康研究等领域。
工作原理
YX-PM2.5颗粒物在线分析仪由采样单元、测量分析仪单元、控制单元等部分组成。采样单元连续不断地以恒定流量采集样气并输送到测量分析单元;测量分析单元通过放置在β射线放射源和探测器之间的滤纸捕捉样气中的悬浮颗粒物,探测器检测透过滤纸后的β射线强度,经过分析处理后,获得空气中的悬浮颗粒物浓度;控制单元完成分析仪的信号采集与输出、流量调节和控制、滤纸行走、环境补偿等功能。
产品特点
● 测量精度高、抗干扰能力强、易于扩展升级;
● 结构简单,采样单元和测量分析单元一体化设计;
● 测量过程无需移动滤纸,提高测量精度和准确性;
● 实时显示当前PM2.5的质量和浓度;
● PM2.5切割粒径准确,内涂硅脂有效滤除大颗粒物;
● 流量自调节技术,快速、精确、稳定的控制流量;
● 温度、压力、湿度补偿技术,消除外界环境影响;
● 人性化设计,触摸控制界面,操作简便;
● 自诊断功能,自动检测仪器各部分是否正常运行;
● 模块化设计、智能化操作、使用寿命长、维护量低。
