Introduction The Model 451P Ion Chamber Survey Meter (the Survey Meter) is a hand-held, pressurized, battery operated meter designed to measure gamma and x-ray radiation above 25 keV, and beta radiation above 1 MeV, using the latest CMOS and LCD technology. The Survey Meter case is constructed of high strength ABS plastic. A gasket seals moisture out of the Survey Meter and provides a cushion for the internal components. The readout consists of a 2½ digit liquid crystal display and a 100 segment analog bar graph. The bar graph contains a zero segment and twenty groups of five segments each....

Ion Chamber Survey Meter Features Features The following sections describe the features of the Survey Meter. Overrange Rate If the instantaneous radiation rate measured by the Survey Meter exceeds 5 R/h, the 'R' in 'mR/h' or the 'Sv' in 'Sv/h' displayed will blink to notify the user that a potential error in the integrated radiation value exists. The blinking will stop when the integrated value is cleared. This, however, may also clear the log data RAM. Low Battery Indicator There are about 6 hours of operation remaining when the LOW BATTERY indicator first becomes visible. When the LOW...
