Digilert200 Survey Meter

 

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.

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.
