Digital Area Monitor

With built-in GM Gamma Detector for continuous monitoring

• Detects gamma radiation
• LOW and HIGH alarms with yellow and red lights, adjustable audible tones
• 0.1 mR/hr - 1000 mR/hr or 1 µSvh - 9999 µSv/h
• Detector failure light and tone to signal detector overload or instrument failure
• Threshold adjustment from 2 to 100 mV
• Battery continuously trickle charges when unit is operating and connected to wall current
• Low battery warning 

• Internal Detector: Halogen quenched GM gamma detector, sensitivity: 1000 cpm/mR/hr (Cs-137 gamma), energy response (60 keV - 3 MeV): within ±25% of true valueDisplay: Four-digit LED display with 0.8" (2 cm) character height
• Display Range: 000.0-9999
• Display Units: Available in mR/hr or µSv/h
• Linearity: Reading within ±10% of true value with detector connected
• Response: Typically three seconds from 10% - 90% of final reading
• Status: (Green light) instrument functioning properly
• Alarm: Low alarm - indicated by yellow light and slow beep (one per second) audible tone (can be set at any point from 0.0 - 9999); high alarm - indicated by red light and fast beep (4 per second) audible tone (can be set at any point from 0.0 - 9999); NOTE: Audible indicators can be configured as a single beep if desired
• Det Fail: Detector overload, no count from detector, or instrument failure - indicated by red light and audible tone (greater than 68 dB at 2 feet)
• Low Bat: (Yellow) indicates less than two hours of battery power remaining
• High Voltage: Adjustable from 200 - 2500 volts
• Threshold: Adjustable from 2 - 100 mV
• Dead Time: Adjustable to compensate for dead time of detector and electronics (can be read on display)
• Overload: Senses detector saturation (indicated by display reading "-OL-")
• Overrange: Indicates radiation field being measured has exceeded counting range of instrument (indicated by display reading "- - - -")
• Data Output: 9 pin connector providing 5 decade logarithmic output,
  RS-232 output, signal ground connection, FAIL and ALARM signals
  (current sink), and direct connection to battery and ground
• Calibration Controls: Accessible from front of instrument
  (protective cover provided)
• Power: 90-260 VAC auto ranging or battery power
• Battery Life: Typically 48 hours in non-alarm condition;
  12 hours in alarm condition
• Battery Charger: Battery is continuously trickle charged when instrument is connected to line power and turned on
• Battery Dependence: <3% change in readings to battery endpoint
• Construction: Wall mount aluminum housing with ivory polyurethane enamel paint
• Dimensions: 7.4" h x 9.7" w x 2.5" depth (18.7 x 24.6 x 6.4 cm)
• Weight: 6.7 lb (3 kg)
