SE International Monitor 4EC 방사선 검출기 (0-50 mR/hr, M4EC)

Detector: Halogen-quenched GM tube, energy compensated sidewall 2mm tin filter. Thin mica window 1.5-2.0 mg/cm2 thick.

Energy Sensitivity

1000 CPM/mR/hr (Cs137). 4EC 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.

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)

Accuracy

Typically ±15% of reading (Cs137)
