Hand Held Survey Meters : Digilert 50
Digilert 50 The Digilert 50 measures alpha, beta, gamma, and x-rays. Its digital display shows readings in your choice of counts per minute (CPM) or mR/hr, or in accumulated counts. A red LED flashes and beeper sounds with each count detected. An audible alert sounds when the radiation reaches a user set alert level.
Specifications:
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 50
CPM: 0 to 50,000
Total: 0 to 60,000 counts
Optional - µSv/hr: .01 to 500
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.
Accuracy: +/-10% typical, +/-15% maximum.
Alert: Pulsating beeper sounds the alert. Three separate adjustable alert levels are used for mR/hr, CPM, µSv/hr:, and Total.
Count Light: Red LED flashes with each count.
Audio Indicator: Sounds with each count (can be switched off for silent operation).
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 is typically 2000 hours at normal background radiation levels.
Temperature Range: -10° to +50°C (14° to 122° F)
Weight: 117 grams (6.5 oz.) without battery.
Size: 150 x 80 x 30 mm (5.9 x 3.2 x 1.2 inches).
Includes: Carrying Case, 1 year limited warranty and CE mark.
Options: Belt Clip
