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
