SE INTERNATIONAL HAND HELD RADIATION DETECTOR MONITOR 4EC

Description

• The M4 or M4EC are both 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. The Monitor 4EC offers a more linear reading for gamma and x-rays (above 40 keV).  

• Detector

• Monitor 4:

• 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.).

• Monitor 4EC:

• Halogen-quenched GM tube, energy compensated sidewall 2mm thin filter. Thin mica window 1.5-2.0 mg/cm2thick. 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

• 1000 CPM/mR/hr (Cs137). M4EC is the same as M4 except the energy response for gamma and x-rays through the detector sidewall is flat within +61% or -26% over the range of 40 keV to 100 keV, and within +35% or -17% over the range of 100 keV to 1.3 MeV. M4 & M4EC meter scales shown below.
  Both Detect beta at 50 keV with typical 35% detection efficiency and beta at 150 keV with typical 75% detection efficiency.

• Accuracy

• Typically ±15% of reading (Cs137)

• Range Switch

• X1, X10, X100, Battery Check.

• Analog Meter holds full scale in fields as high as 100X maximum reading. CPM & mR/hr scale. Optional SI Scale Meter Available
