The Digilert 100 measures alpha, beta, gamma, and x-rays. Its digital display shows readings in your
choice of counts per minute (CPM), mR/hr, or in accumulated counts. A red LED flashes and beeper
sounds with each count detected and when the radiation reaches a user set alert level.
Specifications
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.
Display
4-digit liquid crystal display with mode indicators. Display
updates every 60 sec.
Count Light
Red LED flashes with each count.
Audio Indicator
Sounds with each count (can be switched off for silent operation).
Alert
Pulsating beeper sounds the alert. Three separate adjustable
alert levels are used for mR/hr, CPM, µSv/hr:, and
Total.
Outputs
Dual miniature jack sends counts to CMOS- compatible
devices, including computers, data loggers, and
educational data collection systems. Submini jack
provides audio output to an external earpiece, amplifier,
or tape recorder.

±15% of reading.
Anti-Saturation
Readout will hold at full scale in high radiation fields as high as 100 times the maximum reading |
Energy Sensitivity
1000 CPM/mR/hr (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. |
