For general radiation surveys over a broad range of energies

  •  Alpha, beta, gamma surveying, sample counting
  •  Range: 0 – 500K cpm, 0-2 R/hr
  • 30 mV Threshold
  • Four multipliers: x0.1, x1, x10, x100
  • Meter with probe weighs only 4.5 pounds

The Model 3 with Pancake GM Probe is widely used for general radiation surveying. It is especially useful for collect-ing surface contamination measurements. In detecting medium to high-energy beta-gamma radiation, the pancake GM probe has greater sensitivity to low levels of radiation and has higher counting efficiency than end-window detectors. The Pancake GM Probe is a preferred GM detector for beta emitters with max energy =150 keV. The durable and easy to handle Model 3 Survey Meter has four multipliers, voltage adjustment from 200 to 1500 volts, and typically delivers 2,000+hours of service on one pair of D-cell batteries.
