S.E. International Monitor 200 Compact Radiation Detector

The Monitor 200, your go-to solution for precise and versatile radiation detection. This state-of -the-art device measures alpha, beta, gamma, and x-rays providing accurate readings displayed in your preferred unit of measurement. Choose from CPM, CPS, μSv/hr, mR/hr, or in accumulated counts.

Featuring a digital backlit display, the Monitor 200 ensures easy readability in any environment. The addition of a red count light and an audible beeper accompanying each count detected enhances your awareness during radiation monitoring. With an adjustable timer and customizable loud alert, this radiation detector is tailored to meet you specific needs, offering both accuracy and user-friendly functionality.

Detector

• Halogen-quenched GM tube with thin mica end window. Mica window density 1.5-2.0 mg/cm2. Effective window diameter is 0.360 in. Side wall is 0.012 in. 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

• Referenced to Cs137
• Typically ±15% from factory, ±10% (NIST)

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.

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.
