Model
Digilert 100
Detector
Halogen-quenched GM tube with 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
Operating Range
mR/hr: .001 (1 µR) to 100
CPM: 0 to 100,000
Total: 0 to 120,000 counts
Optional - µSv/hr: .01 to 1000
Accuracy
+/-10 typical, +/-15 maximum.
Energy Sensitivity
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. Normal background is 5-20 CPM.
Gamma Sensitivity
1000 CPM/mR/hr referenced to Cs-1 37.
Count Light
Red LED flashes with each count.
Audio Indicator
Sounds with each count (can be switched off for silent operation)
Alert
Readout will hold at full scale in high radiation fields as high as 100 times the maximum reading
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.
Anti-Saturation
Readout will hold at full scale in high radiation fields as high as 100 times the maximum reading
Power
One 9-volt alkaline battery.
Battery Life
Battery life is typically 2000 hours at normal background radiation levels
Temperature Range
-10° to +50°C (14° to 122° F)
