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 unit also includes an adjustable timer and a loud, customizable alert. With the addition of Bluetooth BLE and the included Observer BLE App, taking, saving, and sending measurements on the go has never been easier. With the free Observer USB Software for PCs, users can set computer alarms, and download your collected data from the internal memory for easy reporting!

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 2000 CPM – 0 to 235,400 CPS – 0 to 3923 Total Counts – 1 to 9,999,000 counts Accuracy Typically ±15% from factory, ±10% (NIST)Energy Sensitivity1070 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. Anti-Saturation Readout will OVERRANGE in radiation fields as high as 100 times the maximum reading. Selectable Alert Set Range mR/hr .001 – 100 and CPM 1 – 350,000. Pulsating beeper sounds the alert. Adjustable alert levels are used for mR/hr / CPM, and µSv/hr / CPS. 70db @ 1m. Alarm will sound when in Timer Mode when set alarm threshold is reached.
