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, easy to read backlit display, a red count light, and a beeper that sounds with each count detected. This radiation detector device also includes an adjustable timer and a loud, customizable alert.
Free Observer USB Software
Free Observer BLE Software For Use With The
Optional Bluetooth Module
Internal memory and the free Observer USB Software (Windows® only) allow you to download your data, and set computer alarms. With the optional Blue Tooth module you can download Free Radiation Alert® Observer BLE app from the Google App Store, where you can display the readings from your detector on your android device, label sample readings and descriptions, take timed counts, append GPS data and send your saved survey file. Alarms set on the instrument will also activate on your android device.
Applications & Uses: Checking accelerator & x-ray shielding for leakage, industrial gauges containing Cesium-137, Locating Sources, Personal protection, General surveying
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.
mR/hr – .001 (1µR) to 200 mR/hr
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.
