The Ludlum Model 375-30 area monitor consists of two shielded 3 in. x 1 in. NaI detectors connected to the modern, lightweight Ludlum Model 375 digital, microprocessor, alarming monitor. Options include strobe lights, horns, remote displays, ethernet PC connection, software and cameras. This system is typically located at the scale/entrance area. The system will continuously monitor incoming materials for radiation. The shielded NaI scintillation are perfect for rugged environments. For clean, indoor environments, consider this system with sleek, compact plastic scintillation tube panels: Model 375-P-336.
