Digilert 100 Handheld Radiation Detector


The Digilert 100 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 and 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.

  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, uSv/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.

  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 - -10degC to +50degC (14degF to 122degF)

  Weight - 117 grams (6.5 oz.) without battery.

  Size - 150 x 80 x 30 mm (5.9 x 3.3 x 1.2 in.).


  Operating Range:

mR/hr - .001 (1uR) to 100 mR/hr
uSv/hr - .01 to 1000
CPM - 0 to 350,000
CPS - 0 to 5000
Total/ Timer - 1 to 9,999,000 counts

  Gamma Sensitivity 1000 CPM/mR/hr referenced to Cs-1 37.

  Accuracy +/-10% typical (NIST), Typically +/-15% of reading.

  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.
