Detector
Halogen-quenched GM tube with thin mica end window. Mica window density 1.5-2.0 mg/cm2.
Effective window diameter is .360 inch. Side wall is .012 inch thick.
Operating Range
mR/hr - .001 (1µR) to 1000 mR/hr
µSv/hr - .01 to 10000
CPM - 0 to 450,000
CPS - 0 to 7500
Total Counts- 1 to 9,999,000 counts
Accuracy (Referenced to Cs-137)
Typically ±15% from factory,
±10% with NIST Source
Calibration
Energy Sensitivity
450 CPM/mR/hr referenced to Cs-137
Selectable Alert Set Range
Alarm can be set in any mode. Pulsating beeper sounds the alert. 70db at 1 m. Alarm will sound when
in Count 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 second. At low background levels, 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
Graphic Display with Backlight
Count Light
Red LED flashes with each radiation event
Audio Indicator
Internally mounted beeper (can be switched off for silent operation)
Outputs
USB and Bluetooth BLE (4.1) for use with Free Observer Family Software for PCs and Android OS.
Power Requirements
Two AA alkaline batteries (included). Approximately 800 hrs at background.
