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.
Operating Range:
mR/hr - .001 (1µR) to 100 mR/hr
µSv/hr - .01 to 1000
CPM - 0 to 350,000
CPS - 0 to 5000
Total/ Timer - 1 to 9,999,000 counts
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 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:
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.
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)
Weight:
117 grams (6.5 oz.) without battery.
Size:
150 x 80 x 30 mm (5.9 x 3.3 x 1.2 in.)
SHIPPING TIMES:
Most, but not all orders leave our warehouse within 1-7 business days. Allow time from the day we ship for UPS or the USPS to deliver it to you from Upstate NY. Please call for rush orders before 2:00 Eastern time. That means that some items, to some locations could take two weeks or more. Remember, we're a 50 year old family run business, so feel free to call us for a rush. We can get most of our items out the same day and use next day air and get it to you tomorrow, but you need to call before 2:00 Eastern time.
