• Radiation Alert® Monitor 1000EC

    Easy to use, energy compensated radiation detector for a wide array of applications for gamma and x-ray detection. Automate surveys with the included Observer Family of PC and Android Software.

Monitor 1000EC / Energy Compensated Radiation Detector - y x

Monitor 200

The Monitor 1000EC measures gamma, and x-rays. Perfect for most applications requiring an energy compensated detector. Users can choose from readings of CPM, CPS, µSv/hr, mR/hr, or in accumulated counts. It has a red count light, a beeper that sounds with each count detected, and includes an adjustable timer, and selectable alert. With the free Observer Software for PCs and Android OS, you can automate and record readings for easy reporting!
Monitor 1000EC Quick Specs


Energy Compensated Halogen-quenched GM tube.

Operating Range

mR/hr - .001 (1µR) to 1000 mR/hr
µSv/hr - .01 to 10000
CPM - 0 to 450,000
CPS - 0 to 7500
Total Counts - 1 to 9,999,000 counts


Typically ±15% from factory, ±10% (NIST)

Energy Sensitivity

450 CPM/mR/hr referenced to Cs137. Detects gamma and x-rays down to 40 keV. Response is flat from 40 keV up.


Readout will OVERRANGE in radiation fields as high as 100 times the maximum reading.

Selectable Alert Set Range

mR/hr .001 - 1000 and CPM 1 - 450,000. 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.
