Radioactivity Detector Radiation Alert SE International MONITOR 200

| 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 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!

• µSv/hr -0 .01 to 2000
• CPS - 0 to 3575
• Total Counts- 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 efficency at 3.6 MeV is greather 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 through the detector window. , 40 keV minimum though the case.

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.
