Model 14C Survey Meter with Pancake Probe

Description

The portable Model 14C Survey Meter with Pancake GM Probe meets the essential monitoring and surveying needs of most nuclear medicine facilities. The external pancake probe is used to check hands, clothing, floors, furniture, equipment, and package surfaces for contamination. For background readings, the unit’s built-in energy-compensated GM detector handles counts up to 2 R/hr. For beta emitters, the pancake probe has approximately twice the counting efficiency as an end-window detector. For high-range gamma detection, the internal detector with the x1000 multiplier range is used. 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.
