技术指标 TSP PM2.5 PM10 都一样，每一台只能测一种参数

　　1.产品简介

　　扬尘在线检测仪(β射线)使用β射线法来实现对大气颗粒物浓度的监测。本产品执行标准如下所示:

　　HJ/T 374—2007 总悬浮颗粒物采样器技术要求及检测方法

　　HJ/T 93-2013 环境颗粒物(和)采样器技术要求及检测方法

　　HJ 1100-2020 环境空气中颗粒物(和)β射线法自动监测技术指南

　　2.工作原理

　　采用的是贝塔射线吸收法的工作原理，将C-14作为发射源，其发射恒定的高能量电子，样品空气通过切割器以恒定的流量经过进样管，颗粒物截留在滤膜上。β射线通过滤膜时，能量发生衰减，通过对衰减量的测定计算出颗粒物的质量，根据采样流量、采样时间和滤膜面积来计算实际状态下环境空气中颗粒物的浓度。该设备适用于建筑工地、道路施工、工厂厂界等颗粒物的在线监测。
 

　　3.产品特点

　　1)使用智能加热技术对采样空气动态加热除湿，提高测量精度。

　　2)使用PID恒流算法，泵转速调控自适应，保证采样空气流量稳定精准。

　　3)使用五校准法，确保PM10浓度无论高低皆能准确测量。

　　4)使用全程零点校准，保证每一次测量都不受滤纸均匀度的影响。

　　5)采样周期连续可调，zx周期3分钟，zd周期60分钟

　　6)支持省纸模式，滤纸可根据使用情况循环利用，能有效延长滤纸使用时间。

　　7)支持本地数据查询展示，可查询任意时间段数据。

　　8)支持有线网络通信和4G无线通信

　　9)支持远程系统升及参数设置

　　10)支持本地数据存储，数据存储时长可达365天。
