Detector: Energy Compensated Halogen-quenched GM tube.
Operating
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
Energy Sensitivity: 450 CPM/mR/hr referenced to Cs137. Detects gamma and x-rays down to 40 keV. Response is flat from 40 keV up.
Accuracy (Referenced to Cs137): Typically ±15% from factory, ±10% with NIST Source Calibration
Anti-Saturation: Readout will OVERRANGE in radiation fields as high as 100 times the maximum reading.
Selectable Alert Set Range: mR/hr .001 – 1000 and CPM 1 – 450,000. Pulsating beeper sounds the alert. Adjustable alert levels are used for mR/hr / CPM, and µSv/hr / CPS. 70db @ 1m. Alarm will sound when in Timer Mode when set alarm threshold is reached.
Display: Graphic LCD with Backlight.
