A standard survey instrument for nuclear medicine departments, the portable Model 14C Survey Meter with End-window Probe meets the essential surveying needs of most nuclear medicine facilities. The end-window probe is used to check hands, clothing, packages, and other surfaces for contamination, and for background readings. For high-range gamma detection, the built-in energy-compensated GM detector with the x1000 multiplier range handles counts up to 2R/hr. The meter features a built-in speaker with ON/OFF switch, front-access calibration controls, push-button reset to zero the meter, and a toggle switch to select FAST (4 sec.) or SLOW (22 sec.) response.
