The SE International Monitor 4 and 4EC are hand-held radiation detectors that detect harmful alpha, beta, gamma, and x-ray radiation. These Geiger counters are used to detect radiation levels of particulate accelerators, x-ray shielding and industrial gauges. Both detectors have three operating levels (X1, X10 and X100) that can be adjusted when the meter peaks at the highest mR level. When the device detects an ionizing radiation event, a red light will flash and a beeping noise will sound.
Monitor 4 uses a halogen-quenched uncompensated GM tube detector. Monitor 4EC features a halogen-quenched GM tube, energy compensated sidewall and 2mm thin filter.
