Description

粉尘采样器是一种测定一个工班内空气粉尘平均浓度的仪器。该仪器根据GB/T20964-2005《粉尘采样器通用技术条件》、Q/320581SXYB006-2018个体粉尘采样器技术条件及GB3836.4-2000标准中ExibI等级(本质型)设计,具有采样气流脉动小、负载能力大、流量稳定、操作简单、便于携带等特点,对呼吸性粉尘的分离效能符合“BMRC”标准曲线要求,特别适用于煤矿井下及其他含有危险性气体的作业场所使用。

 

1 采样流量:呼吸性粉尘采样时:2L/min(流量固定)

 

2 采样流量误差:≤3%FS

 

3 采样流量稳定性:采样器8小时内采样流量稳定性≤3.0%FS

 

4 负载能力:≥1000Pa

 

5 连续工作时间:≥12h(带负载)

 

6 工作噪声:≤65dB (A)

 

7 气密性:在1000Pa压力下,1min内其压力变化值不得超过100Pa。

 

8 流量计准确度:不低于2.5级。

 

9 采样时间误差:≤0.1%

 

10 采样口平均流速:0.5~4.0m/s

 

11 采样准确度:≤10%

 

12 采样效能:符合“BMRC”采样效能曲线,采样效能允许误差应符合表2规定。
