Inspector Survey Meter

078-513-blue Inspector Survey Meter
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. Additional benefits include an adjustable timer and external calibration controls. Now with USB and the included Observer USB Software, you can download your data from the internal memory, set computer alarms and calibrate your instrument.

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 locations 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.

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

  • Count range: 1 to 9,999,000 counts
  • Range: 0-350,000 cpm
  • Red LED count light
  • Audible beeper (can be switched off)
  • External calibration controls
  • Adjustable timer from 1 to 24 hours; default is 10 minutes
  • User selectable display for mR/hr or Sieverts
  • Internal Memory
  • Observer USB Software – can be downloaded
  • Includes case
  • 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

  • Detector: Halogen-quenched uncompensated GM tube with thin mica window, 1.4-2.0 mg/cm2 area density.
  • Window: 1.77″ (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: 3340 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; CPM – 0 to 350,000
    – µSv/hr – .01 to 1000; CPS – 0 to 5000
  • Energy Sensitivity: Detects Alpha down to 2 MeV. Detects Beta down to .16 MeV; typical detection efficiency at 1 MeV is approx. 25%.
  • Accuracy (Referenced to Cs-137): Typically ± 15% from 0 to 100 mR/hr
  • Timer: One minute to 24 hours, default is 10 minutes
  • 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
  • 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, adjust probe settings, 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
  • Built-In Efficiencies: 5Sulfur (S35), 90Strontium (Sr/y90), 137Cesium (Cs137), 32Phosphorus (P32), 14Carbon (C14), 131Iodine (I131), 60Cobalt (Co60), and Alpha
  • Power Requirements: (1) 9-volt alkaline battery.
  • Temperature Range: 14°F to 122°F (-10°C to +50°C)
  • Battery Life: Typically 2000 hours at normal background radiation levels
  • Dimensions: 5.9″ h x 3.2″ w x 1.2″ d (15 x 8 x 3 cm)

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)
