- The hand-held unit measures alpha, beta, gamma, and x-rays. Its digital display shows readings in your choice of counts per minute (CPM), CPS, μSv/hr, mR/hr, or in accumulated counts.
- With USB and the included Observer USB Software, you can download your accumulated data from the internal memory, set alarms, and calibrate your instrument!
- It uses a Halogen-quenched GM tube with thin mica end window detector.
- The mica window density is: 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 200 mR/hr
μSv/hr – .01 to 2000
CPM – 0 to 214,000
CPS – 0 to 3575
Total/ Timer – 1 to 9,999,000 counts
Accuracy
±10% typical (NIST), Typically ±15% of reading.
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.
