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
