上海探伤机厂产的DK—60空气微尘取样器是专供厂矿、科研、医疗、劳动卫生等单位在无电源地区作空气微尘取样用。此外,还被广泛用于空气中放射性气溶胶取样。原设计使用电压为8～12伏、电流约3～5.5安。由一组4～6节锌银蓄电池供电。虽然锌银蓄电池有体积小、重量轻且容量大的优点,但其价格昂贵,要经常充电,保养较麻烦,极易损坏(一 Shanghai Flaw Detector Factory production DK-60 air dust sampler is designed for factories and mines, scientific research, medical treatment, labor and health and other units in the absence of power for air samples for dust sampling. In addition, it is also widely used in aerosol sampling of air. The original design voltage of 8 to 12 volts, the current is about 3 ~ 5.5 amps. By a group of 4 to 6 zinc-zinc batteries. Although zinc-silver batteries have the advantages of small size, light weight and large capacity, they are expensive, often charged, trouble-free maintenance, and easily damaged
