  • $499.90
  • Save $300

This is a brand new DT-9501 CE certified digital radiation scanner/meter from CEM.  The DT-9501 Handheld Multi-function Digital Radiation Detector is designed strictly following new standards. This product is made with the highly-sensitive Geigai counter sensor and the latest CMOS integrated circuit technology. The product has functions such as data logging, Bluetooth communication for data transmission, and powerful software for data analysis. It can detect Alpha, Beta, Gamma and X ray; it also can detect radiation pulse times. This meter can be widely used in the field of pharmaceutical production, laboratories, power stations, stone pits, emergency rescue stations, metal plants, oil field and oil pipeline equipment, environmental protection, police departments and more.

DT-9501 is mainly used to detect groundwater radiation, radium pollution, radioactivity of underground drill pipe and equipment, radon radiation, cesium pollution, radioactivity of construction materials, radioactivity of porcelain, tableware and glass, local radiation leaks, nuclear radiation pollution , landfill and dumps with risk of nuclear radiation, radioactive houses construction materials, office building construction materials, harmful radiation of personal property and valuable jewelry, X-ray Intensity in medical and industrial usage and facilities.
