SE International Monitor 4 EC

SE International Monitor 4EC Radiation Detector

The M4EC is a 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

Thin window Geiger-Muller

Sensitivity

Detects alpha down to 2.5 MeV; typical detection efficiency at 3.6 MeV is greater than 80%. Detects gamma and x-rays down to 10 keV typical through the window (non-compensated), 40 keV through the sidewall.

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

Accuracy

Typically ±15% of reading (Cs137)

Detector Type
