- 1 mR/hr to 4 R/hr (Model 05-444) Features Introduction The PRIMALERT Digital Area Monitors are designed for a wide range of radiation area monitoring applications. They are completely self-contained units with energy compensated GM detectors, AC powered with internal battery backup and have user settable low and high alarms. An optional remote alarm is available for added security. Applications The PRIMALERT Digital Area Monitors can be used wherever there is a need to detect and warn personnel of increasing radiation levels and to control the exposure of personnel to gamma radiation. The versatility of the PRIMALERT allows it to be used from industrial applications to medical settings. |
| Specifications Detector Indicated use Radiation area monitoring Internal GM detector range: Model 05-443 0.1 mR/hr to 1 R/hr; Model 05-444 1 mR/hr to 4 R/hr Display 4 digit LED display with .8 in (2 cm) character height Display range 000.0 to 9999 Display units Can be made to display in µR/hr, mR/hr, R/h, µSv/h, mSv/h, Sv/h, cpm, cps and others Linearity Reading within ±10% of true value with detector connected Response Typically 3 seconds from 10% to 90% of final reading Status (green light) Indicates the instrument is functioning properly Low alarm Indicated by a yellow light and slow beep (1 per sec) audible tone (can be set at any point from 0.0 to 9999) Note; audible indicators can be configured as a single beep if desired Detector fail (red light and audible tone; > 68 dB at 2 ft) Indicates detector overload, no count from detector, or instrument failure Low battery (yellow) Indicates < 2 hours of battery power remaining Calibration controls Accessible from front of instrument (protective cover provided) High voltage Adjustable from 200 to 2500 V Threshold Adjustable from 2 to 100 mV Dead time Adjustable to compensate for dead time of the detector and electronics (can be read on the display) Overload Senses detector saturation (indicated by display reading "-OL") Overrange Indicates the radiation field being measured has exceeded the counting range of the instrument (indicated by display reading "----") Data output 9 pin connector providing 5 decade log output, RS-232 output, signal ground connection FAIL and Alarm signals (current sink), and direct connection to battery and ground |
