Description 

The Monitor 200 measures alpha, beta, gamma, and x-rays. Its digital display shows readings in your choice of CPM, CPS, μSv/
hr, mR/hr, or in accumulated counts. It has a digital display, a red count light, and a beeper that sounds with each count detected. Other features include an adjustable timer, and selectable alert. With the free Observer USB Software Family, you can set computer alarms, calibrate your instrument, and download your collected data from the internal memory for easy reporting!

Detector Halogen-quenched, uncompensated Geiger Muller tube with thin mica window, 1.5-2.0 mg/cm2 areal density.
Effective diameter of window is 0.360 inches. Side wall is 0.12 inches thicck
Ranger
(Internal tube only)
Radiation symbol on front label marks the center of the detector.
Display: Graphic Display with backlight
Averaging periods: Display will update every 3 seconds. At low background levels, the update is the moving average for the past 30-second time period. The timed period for the moving average decreases as the radiation level increases.
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
Accuracy (Referenced to Cs137) Typically ±15% from factory, ±10% with NIST Source Calibration
Energy Sensitivity 1070 CPM/mR/hr referenced to Cs137
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.
Timer Can set 1 minute sampling periods from 1 to 10 minutes. 10 minute sampling periods 10- 60 minutes. 1 hour sampling periods from 1 to 24 hours.
Count Light Red LED flashes with each radiation event.
Audio Indicator Internally mounted beeper (can be switched off for silent operation).
Outputs USB for use with Free Observer USB Software for PCs
Anti-Saturation Meter will hold at full scale in fields as high as 100 times the maximum reading.
Power Requirements AA alkaline batteries.
Temperature Range -10ºC to 50ºC (14ºF to 122ºF)
Size 140 X 68 X 33 mm (5.5 X 2.7 X 1.3 in.)
