Digital Radiation Monitor

Product code: MH335

Category: Miscellaneous Equipment and Hardware

with adjustable alert level alarm 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.
