Operating Range

mR/hr – .001 (1µR) to 200 mR/hr

µSv/hr – .01 to 2000

CPM – 0 to 235,400

CPS – 0 to 3923

Total Counts – 1 to 9,999,000 counts

Energy Sensitivity

1070 CPM/mR/hr referenced to Cs137

Detects alpha down to 2.5 MeV; typical detection efficiency at 3.6 MeV is greater than 80%.

Detects beta at 50 keV with typical 35% detection efficiency.

Detects beta at 150 keV with typical 75% detection efficiency.

Detects gamma and x-rays down to 10 keV typical through the window, 40 keV minimum through the case.

Accuracy of Radiation Detector Device

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 – 100 and CPM 1 – 350,000. 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.
