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
The Inspector is a microprocessor controlled radiation measuring instrument which offers excellent sensitivity to low levels of alpha, beta, gamma and x-rays. The digital readout is displayed with a red count light and audible beep, providing instant indications of the radiation level. Other benefits include an adjustable timer and external calibration controls.

Shielded Holder

Maintain full function of the 078-513 Inspector Survey Meter while shielding it laterally to reduce the influence of background radiation. Constructed of steel with 0.5" thick lead lining built into left and right sides, the holder conveniently supports the Inspector while allowing full operation of the optional sliding wipe test plate -- without having to lift the meter. This accessory is especially suited for use in mobile units, or where the meter is frequently used for standardized procedures in a single location. The unit is supplied with strips of reclosable fastening material for affixing to countertops or other surfaces.

  • 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
078-514 Inspector Survey Meter Shield:
  • Dimensions: 10.3" l x 4.8" w x 1.5" h (26 x 12 x 4 cm)
  • Construction: Steel, with lead lining in left and right side walls
  • Lead Shielding: 0.5" thick (1.3 cm) laterally
  • Weight: 7.8 lb (3.5 kg)
