Inspector Survey Meter

Low-level radiation sensitivity in a compact hand-held unit

• Monitors alpha, beta, gamma, and x-ray radiation
• Range: 0-300,000 cpm
• 4-digit LCD readout
• Red LED count light
• Audible beeper (can be switched off)
• External calibration controls
• Adjustable timer with:
  1-minute sampling periods from 1 to 10 minutes
  10-minute sampling periods from 10 to 60 minutes
  1-hour sampling periods from 1 to 24 hours
• Operates 200 hours on 9V battery
• Wipe Test Plate positions wipe directly in front of detector at 1 cm distance; protects GM from
  damage/contamination when meter is not in use
• User selectable display for mR/hr or sieverts 

• Detector: Halogen-quenched uncompensated GM tube with thin mica
  window, 1.4-2.0 mg/cm2 area density.
• Window: 1.75" (45 mm) effective diameter
• Display: Four-digit liquid crystal display with indicators
• Averaging Periods: Display will update every three seconds; at low background levels, the update is the moving average for the past 30-second time period; time period for moving average decreases as radiation level increases
• Gamma Sensitivity: 3500 cpm/mR/hr (referenced to Cs-137); smallest detectable level for I-125 is .02 µCi at contact
• Operating Range:
  mR/hr - .001 (1µR) to 100 mR/hr
  µSv/hr - .01 to 1000
  CPM - 0 to 300,000
  CPS - 0 to 5000
  Total/ Timer - 1 to 9,999,000 counts
• Accuracy (Referenced to Cs-137):
  mR/hr ± 15% from 0 to 30 mR/hr, ± 20% from 30 to 50 mR/hr
  CPM ± 15% from 0 to 100,000 cpm, ± 20% from 100,000 to 300,000 cpm
• Timer: Can set 1-minute sampling periods from 1 to 10 minutes, 10-minute sampling periods from 10 to 60 minutes, 1-hour sampling periods from 1 to 24 hours
• Count Light: Red LED flashes with each radiation event
• Audio Indicator: Internally mounted beeper (can be switched off for silent operation)
• Outputs: Dual miniature jack drives CMOS or TTL devices for counting to computer or data logger; (Submini jack input allows for electronic calibration)
• Utility Menu: Options accessed by holding down "+" button while turning instrument on: 3-second (fast response), switch from mR/hr and CPM to µSv/hr and CPS, reset cal factor to 100, adjust probe settings, adjust the CAL factor, reset all setting to original factory setting (default)
• Anti-Saturation: Meter will hold at full scale in fields as high as 100 times the maximum reading
• Power Requirements: (1) 9-volt alkaline battery
• Temperature Range: 14°F to 122°F (-10°C to +50°C)
• Battery Life: Typically 200 hours at normal background radiation levels
• Dimensions: 5.9" h x 3.3" w x 1.2" d (15 x 8 x 3 cm)
• Weight: 10.6 oz (300 grams) without battery
