The Victoreen 471 Sensitive Wide Range Survey Meter is a more sensitive version of widely accepted model 470A. Featuring a 1 mR/hr full scale sensitivity the 471 is housed in a rugged metal case with all controls and meter conveniently located on the top. Its excellent energy response and wide dynamic range suggest many health physics uses.
