• Detector: Halogen-quenched uncompensated GM tube with thin mica window, 1.4-2.0 mg/cm2 areal density. Effective diameter of window is 45 mm (1.75 in.).
  • Display: 4 digit liquid crystal display with indicators
  • Averaging Periods: Display will update every 3 seconds. At low background levels, the update is the moving average for the past 30 second time period. Timed period for moving average decreases as the radiation level increases.
  • Operating Range: mR/hr- .001 (1µR) to 100 mR/hr; µSv/hr- .01 to 1000; CPM- 0 to 300,000; CPS- 0 to 5000; Total/Timer- 1 to 9,999,000 counts
  • Accuracy: mR/hr + 15% from 0 to 50 mR/hr; mR/hr + 20% from 50 to 100 mR/hr; CPM + 15% from 0 to 130,000 CPM; CPM + 20% from 130,000 to 300,000 CPM; (Referenced to Cs-137)
  • Sensitivity to Common Isotopes: Typical GM tube efficiency for 4 Pi geometry at contact 

   The Inspector is a small handheld microprocessor based instrument which offers excellent sensitivity to low levels of alpha, beta, gamma, x-rays. The digital readout is displayed with a red count light and audible beep, providing instant indications of the radiation level. Other benefits include an adjustable timer and external calibration controls.
