Area radiation monitoring device 75/1

calibrationfor medical applicationscompact

The Model 375/1 Digital Wall-Mount Area Monitor is designed for visibility and ease of use. This monitor incorporates an internally housed 18 mm CsI scintillator with a sensitivity of approximately 120 cpm per µR/hr. It features a wall-mount chassis and a four-digit LED display that is readable from 9 meters (30 feet) away. Backlit indicators warn of low radiation (yellow), high radiation (red), instrument failure (red), and low battery (yellow), along with an alarm. A green status light indicates the instrument is functioning properly. Parameters are protected under a calibration cover that provide access to adjusting the calibration constant, dead time correction, and alarm point parameters. Parameters are stored in non-volatile memory (retained even with power disconnected). A five-decade logarithmic analog output is provided. Options available include remote displays, an Ethernet port, alarm relay output, and a NEMA 4 outdoor enclosure. Note: While the detector used in this instrument is sensitive and is often used for detection of near-background levels of radiation, its nonlinear energy response means that does and exposure measurements may be over/underreported. Specifications Detector - 18 mm CsI detector (nonlinear energy response, see Energy Response Curve in the Graphs tab) Sensitivity - 120 cpm per µR/hr Measurement Range - 0.1 to 9999 µR/hr (alternately 0.01 to 99.99 mR/hr) Display - 4-digit LED display with 2 cm (0.8 in.) characters Display Units - µR/hr (other units available upon request) Status Indicators - Instrument Status: Green light indicates instrument is functioning properly
