Inspector Survey Meter Biodex
Halogen-quenched uncompensated GM tube with thin mica window, 1.4-2.0 mg/cm² areal density.
1.77" ( 45 mm ) effective diameter
Backlit graphic LCD with backlight
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.
3340 cpm/mR/hr ( referenced to Cs-137 ); smallest detectable level for I-125 is .02 µCi at contact
- mR/hr - .001 ( 1µR ) to 100; CPM - 0 to 350,000
- µSv/hr - .01 to 1000; CPS - 0 to 5000
Detects Alpha down to 2 MeV. Detects Beta down to 0.16 MeV; typical detection efficiency at 1 MeV is approx. 25 %. Detects Gamma down to 10 KeV through the end window.
Accuracy ( Referenced to Cs-137 )
Typically ± 15 % from factory.
One minute to 24 hours, default is 10 minutes
Red LED flashes with each radiation event
Internally mounted beeper ( can be switched off for silent operation )
