Contamination Detector GRAETZ CoMo-170 F

High-performance mobile and battery- or accumulator-powered contamination monitor for highly sensitive nuclide-related measurement of surfaces for α-, β- and γ-contamination when handling ionizing radiation. The one-hand measuring system has a detector area of 170 cm² and automatically detects whether α-radiation is present.
