Inspector Survey Meter Biodex

Specifications

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
