Detector
Monitor 4: Halogen-quenched uncompensated GM tube with thin mica window 1.5-2.0 mg/ cm2
Monitor 4EC: Halogen-quenched GM tube, energy compensated sidewall 2mm tin filter. Thin mica window 1.5-2.0 mg/ cm2 thick.
Range Switch X1, X10, X100, Battery Check.
Accuracy ± 15% of full scale ( referenced to Cs-137)

The MONITOR 4 and MONITOR 4EC are compact, 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, ( energy compensated) offers a more accurate linear reading for gamma and x-rays ( above 40 keV) . Gamma sensitivity is typical of a pancake G-M detector: 1000 CPM/ mR/ hr ( referenced to Cs-137) . Energy Sensitivity for the 4EC is the Same as Monitor 4 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.
