Manufacturer: S.E. International, Inc. Product ID : SE-Digilert200
Overview
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, or mR/hr, or in
accumulated counts. Now with the USB and the Observer USB Software, you
can download your accumulated data form the Digilert200’s internal
memory, set computer alarms, and calibrate your instrument.
Description :Digilert 200 Handheld Digital l Radiation Alert® Detector
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.
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
Gamma Sensitivity: 1070 CPM/mR/hr referenced to Cs-137.
Accuracy: ±10% typical (NIST), ±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 40 keV.
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)
Weight: 217 grams (7.7 oz.) without battery.
Size: 150 x 80 x 31 mm (6.1 x 3.1 x 1.2 in.).
