PRIMALERT® Digital Area Monitors

The PRIMALERT Digital Area Monitors are designed for a wide range of radiation area monitoring applications.

The PRIMALERT Digital Area Monitors are designed for a wide range of radiation area monitoring applications. They are completely self-contained units with energy compensated GM detectors, AC powered with internal battery backup and have user settable low and high alarms. An optional remote alarm is available for added security.

Applications:

The PRIMALERT Digital Area Monitors can be used wherever there is a need to detect and warn personnel of increasing radiation levels and to control the exposure of personnel to gamma radiation. The versatility of the PRIM ALERT allows it to be used from industrial applications to medical settings.
