The Digilert 200 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. Now with USB and the included Observer USB Software, you can download your accumulated data from the Digilert200’s internal memory, set alarms, and calibrate your instrument!


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 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%.
