Product Manual

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 alerts. With the free Observer USB Software Family, you can set up computer alarms, calibrate your instrument and download your collected data from the internal memory for easy reporting. Bluetooth is now available for use with BLE APP and Rad Responder.

This optional accessory was custom designed for use with the Radiation Alert Ranger, Monitor 200 and Monitor 1000EC. Ideal for users whose operational needs are primarily out in the field. Smart design and durable materials.
