DURAG粉尘浓度监测仪F-701-20介绍
环境空气中粉尘质量浓度的测定
C-14法，活动性无明显降低
所有量规中放射性最低的产品，可根据政府法规未经许可使用以处理放射性物质
自动零位校正
样气流量，稳定1m³/ h
吸取恒定的样气流速，与环境温度和压力无关
在同一地点重复采样
收集的灰尘样品可用于成分分析，例如重金属
RS-232接口和模拟输出，状态信号
Determination of dust mass concentration in ambient air independent of matter
C-14 method, no measurable decrease in activity
Lowest radioactivity of all beta gauges, usable without license for handling radioactive substances acc. to governmental regulations
Automatic zero point correction
Sample gas flow, stabilized 1m³/h
Suction of a constant sample gas flow rate independent of ambient temperature and pressure
Repeated sampling on the same spot
Collected dust sample available for component analysis, e.g. heavy metals
RS-232 interface and analog output, status signals
