Alarm monitor – stationary dose rate monitoring system with external detectors


The NuRMS ALMO alarm monitors are used to monitor radiation dose rates in the laboratoryNuRMS ALMO radiation monitoring systems
production facilities.

The systems consist of a basic device with LCD and electronics, combined with one or more probes and external alarm units.

Depending on the version, it is possible to connect 1, 3 or 6 detectors to the NuRMS ALMO basic device.

The stand-alone NuRMS ALMO-systems can be linked to a superior PC-system for central monitoring and documentation.
