Six range indicators (1, 2, 4, 8, 16, and 32 mR/hr) clearly display an increase or decrease in radiation levels. The alarm can be set at any of the six levels by a front panel, screwdriver-adjustable control. Both the visible and audible alarms, or just the visible alarm, can also be set from this panel. The light for each level goes on when the radiation intensity reaches that level, and goes out when the rate drops below the level. This permits instant radiation-level recognition not readily distinguishable on meter-type instruments.
When the preset level is exceeded, personnel are alerted by bright flashing red lights (visible over a 180° field) and a loud intermittent audio signal. The alarms stop automatically when the radiation level falls below the preset value. A front-panel switch permits the selection of both the visible and audible alarms or just the visible alarm.
Fail-safe operation is assured by a light which continuously indicates background radiation and provides visual proof that the unit is functioning. The monitor will not jam or show false readings in high radiation fields. The Primalert 35 contains an energy-compensated GM detector, and features a convenient, automatic alarm reset. A mounting bracket and a 110 volt AC adapter/power converter are also included. The optional Primalarm Remote Alarm provides the same audible and visible signals as the Primalert 35, up to 100 feet from the monitor.
Applications:
Provides continuous visual indication of radiation levels and produces audible and/or visual alarms at any of six presettable radiation levels
Assures reliable, continuous monitoring wherever radioactive materials are present
Displays the radiation level in bright color-coded lights
Emits audible and/or visible signals whenever the gamma radiation exceeds a user-preset alarm level
