Digilert200 Survey Meter

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.).
