Product Code:DIGILERT200


Need more Info? (514) 354-2511 - 1-800-463-4363

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%.
  • 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.
