Product Details

SE Digilert 200 Description:

The Radiation Alert Digilert 200, with its thin end window GM tube, measures alpha, beta, gamma and x-rays. The digital display shows readings in your choice of counts per minute (CPM), counts per second (CPS), µSv/hr, mR/hr or accumulated counts. The operating range is up to 200mR/hr.

With the free, downloadable Observer USB Software, you can download and save accumulated data, set computer alarms and calibrate instruments.

The SE Digilert 200 has been discontinued. Its replacement is:SE Monitor 200

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.
Operating Range: mR/hr - .001 (1µR) to 200 mR/hr
µSv/hr - .01 to 2,000
CPM - 0 to 214,000
CPS - 0 to 3,575
Total Counts - 1 to 9,999,000 counts
Accuracy: Typically ± 15% from factory, ± 10% (NIST).
Energy Sensitivity: 1070 CPM/mR/hr referenced to Cs137
Detects alpha down to 2.5 MeV; typcial detection efficiency at 3.6 MeV is greater than 80%.
Detects beta at 50 keV with typical 35% detection efficiency.
Detects beat at 150 KeV with typcial 75% detection efficiency.
Detects gamma and x-rays down to 10 keV typical through the window. 40 keV minimum through case.
Anti-Saturation: Readout will OVERRANGE in radiation fields as high as 100 times the maximum reading.
Alerts: Pulsating beeper sounds the alert. Adjustable alert levels are used for mR/hr / CPM and µSv/hr / CPS. Alarm will sound when in Timer Mode when set alarm threshold is reached.
Display: Backlit 4-digit liquid crystal display with mode indicators. Display updates every 3 seconds.
Count Light: Red LED flashes with each count.
Audio Indicator: Sounds with each count (can be switched off for silent operation)
Outputs: Dual miniature jack sends counts to CMOS-compatible devices including computers, data loggers and educational data collection systems. USB for use with Observer USB software for PCs.
Temperature Range: -10°C - 50°C (14°F - 122°F)
Power Requirements: One 9-Volt alkaline battery. Battery life is approximately 2,000 hours at normal background radiation levels.
Weight: 217 grams (7.7 oz.)
Dimensions: 150mm x 80mm x 31mm (6.1" x 3.1" x 1.2")
Includes: Carrying Case, Observer USB Software Download, USB Cable and Certification of Conformance
Options: Xtreme Boot and Stand
Limited Warranty: 1 year limited warranty
