Specification of DIGILERT 200 RADIATION ALERT DETECTOR
Digilert 200 measures the radiation in alpha, beta, gamma, and x-rays with digital readout that can diketahu results in a few minutes (CPM), CPS, μSv / hr or mR / hr, or the accumulated amount. Now with USB and USB Obserber Software, you can download the data accumulated to form an internal memory of 200 Digilert this, set the alarm computer, and calibrate your instrument.
L Digilert 200 Handheld Digital Radiation Alert® Detector
Specification
Detector: Halogen-quenched GM tube with thin mica window end. Mica window density
1.5-2.0 mg / cm2. Effective window diameter is 0.360 inches. the side wall is 0.012 inch
thick.
Display: 4-digit liquid crystal display with mode indicator. Display updates every 60 seconds.
Calculating the Light: Red LED flashes with each count.
Indicators Audio: Sounds with each count (can be turned off for silent operation).
Reminded: pulsating beeper sounded wary. Three separate warning adjustable rate used to mR / hr, CPM, μSv / h:, and Total.
Output: Dual miniature jack sends the number to CMOS- compatible devices, including computers, data loggers, and data collection systems of education. Submini jack provides audio output to an earpiece, amplifier, tape recorder or external.
Operating range:
mR / hr - 0,001 (1μR) to 200 mR / hr
μSv / h - 0.01 to 2000
CPM - 0 214000
CPS - 0-3575
Total / Timer - 1 to 9.999 million number
Gamma Sensitivity: 1070 CPM / mR / hr referenced to Cs-137.
Accuracy: ± 10% typical (NIST), ± 15% maximum.
Energy Sensitivity:
Detecting alpha to 2.5 MeV; typical detection efficiency at 3.6 MeV is greater than 80%.
