|
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 |
|
