|Detector: ||Internal Halogen-quenched uncompensated GM tube with thin mica window, 1.4 - 2.0 mg/cm2 areal density. Effective diameter window is 45 mm (1.77"). Radiation symbol on front label marks the center of the detector. |
|Operating Range: ||mR/hr - .001 to (1µR) to 100 |
CPM - 0 - 350,000
µSv/hr - .01 - 1,000
CPS - 0 to 5,000
Total / Timer - 1 to 9,999,000 counts
Accuracy (referenced to Cs137)
Typically ± 15% from factory, ± 10% with NIST source Calibration.
|Energy Sensitivity: ||3340 CPM / mR/hr (Cs137) |
Detects Alpha down to 2 MeV.
Detects Beta down to .016 MeV; typical detection efficiency at 1 MeV is approximately 25%.
Detects Gamma down to 10 keV through the end window.
Smallest detectable level for I125 is .02 µCi at contact.
|Built-in Efficiencies: ||Sulfar (S35), Strontium (Sr/y90), Cesium (Cs137), Phosphorous (P32), Carbon (C14), Iodine (I131), Cobalt (Co60) and Alpha. |
|Selectable Alert Set Range: ||mR/hr - .001 to 50 and CPM - 1 to 160,000. 70db @ 1m. Pulsating beeper sound the alert. Adjustable alert levels are used for mR/hr / CPM and µSv/hr / CPS. Alarm will sound when in Timer Mode when set alarm threshold is reached. |
|Anti-Saturation: ||Meter will hold at OVER RANGE in fields as high as 100 times the maximum reading. |
|Averaging Periods: ||Display updates every 3 seconds. At low background, the update is the average for the past 30 second time period. The timed period for the average decreases as the radiation level increases. |
|Display: ||Backlit 4 digit liquid crystal display with indicators. Display updates every 3 seconds. |
|Count Light: ||Red LED flashes with each radiation event. |
|Audio Indicator: ||Internally mounted beeper (can be switched off for silent operation). |
|Outputs: ||3.5 mm jack for CMOS or TTL devices and counts to a computer or datalogger. USB for use with FREE Observer USB Software for PCs. |
|Temperature Range: ||-10°C - 50°C (14°F - 122°F) |
|Power Requirements: ||One 9-volt alkaline battery or USB - AC Adapter. Battery life is approximately 2,000 hours at normal background. ||One 9-volt alkaline battery. Battery life is approximately 2160 hours at normal background. |
