SE MONITOR 4

Monitor 4 /Analog Radiation Detector – a ss y x
Monitor 4are compact, ergonomic, general purpose survey meters capable of detecting alpha, beta, gamma, and x-rays over 3 selectable ranges. A red count light flashes and a beep sounds with each event detected.

Includes:

• Monitor 4
• Carrying Case w/ Belt Clip

Features:

• Detector
  Halogen-quenched uncompensated GM tube with thin mica window 1.5-2.0 mg/cm2 thick.
  Effective diameter of window is 9.1 mm (.36 in.).
• Operating Range
  0-.5, 0-5, 0-50 mR/hr 0-500, 0-5,000, 0-50,000 CPM or 0-5, 0-50, 0-500 µSv/hr (SI Scale Meter Option)
• Energy Sensitivity
  Detects alpha down to 2.5 MeV; typical detection efficiency at 3.6 MeV is greater than 80%.
  Detects beta at 50 keV with typical 35% detection efficiency.
  Detects beta at 150 keV with typica 75% detection efficiency.
  Detects gamma and x-rays down to 10 keV typical through the window, 40 keV minimum through the case. (GRAPH 1).
  Normal background is 5-20 CPM.
• Accuracy
  Typically ±15% of reading (Cs137)
• Display
  Analog Meter holds full scale in fields as high as 100X maximum reading. CPM & mR/hr scale. Optional SI Scale Meter Available
