PRIMALERT™ 35 Area Radiation Monitor.
The PRIMALERT™ 35 assures reliable, continuous monitoring wherever radioactive materials are present.  It displays the radiation level in bright color-coded lights, and it emits audible and/or visible signals whenever the gamma radiation exceeds a user-preset alarm level.
Features
• Calibrated
• Monitor for Radioactive Material
• Compact
• Lightweight
• Optional PRIMALARM™ Remote Alarm
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.  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.
An optional PRIMALARM™ Remote Alarm (Item 337-138) provides the same audible and visible signals as the PRIMALERT™ 35, up to 100 feet from the monitor.  The PRIMALARM™ allows personnel located away from the radiation area to be alerted the instant the preset radiation limits have been exceeded.
