GM-42 Detector
Sensitive low-range GM gamma detector for clean rooms and radiopharmacies
Sensitive low-range gamma detector for measuring dose rates where radioactive material is handled, such as clean rooms, radiopharmacies, QA departments and packing rooms, and as a backup to the extremely sensitive PM-11 exhaust stack detector. Like all WebiSmarts detectors it contains its calibration factor and a unique electronic identifier.
