Description

一、产品说明:


   DW-3L个体粉尘采样器是一种用以采集粉尘平均浓度的仪器。适用于大气环境监测疾病预防控制、卫生防疫、劳动保护等单位使用。采样头是根据空气动力学与人体呼吸仿真原理,对危害人体的呼吸性粉尘进行有效的分离,其分离效率符合“BMRC”曲线标准。


   该仪器结构紧凑,内置高能锂充电电池连续运转时间长,性能稳定、体积小、重量轻、便于携带,是较为实用的个体粉尘采样仪。


二、技术参数:


1、流量范围:0.1~3L/min


2、流量误差:≤5%


3、流量精度:2.5级


4、采样时间:>8小时


5、定时范围:99小时59分内任意设定


6、定时误差:≤1‰


7、最大负压:≥35000pa


8、工作温度:-25~45℃


9、贮存温度:-40℃~+60℃


10、环境大气压:80KPa~110Kpa


11、噪    声:≤55dB


12、相对湿度:≤85%


13、电    源:7.4VDC、220V50HzAC


14、充电电流:300mA(标准型)
