Digilert 200 Handheld Radiation Detector

The Digilert 200 by SE International is a meter that measures alpha, beta, gamma and x-rays. It backlit 4-digit liquid crystal display counts per minute (CPM), CPS, µSv/hr, mR/hr or the total count, which one is preferred.

With USB connectivity and Observer USB software, you can download the total data from its internal memory, set alarms and adjust your instrument.

Operating Range

  mR/hr - .001 (1�R) 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


+/- 10% typical (NIST), Typically ±15% of reading.

Energy Sensitivity

  1070 CPM/mR/hr referenced to Cs
  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.
