OVERVIEW

The GMP-25 probe is intended for monitoring alpha, beta, gamma and X-ray radiation. The GMP-25 is used as an external detector with the RDS-31/ iTx/iTxSD multi-purpose Radiation Survey Meters especially for surface contamination monitoring and source localization applications.
The GMP-25 probe is equipped with a Binder con- nector and connected to the mating bulk connec- tor interface at the bottom of RDS-31 family survey meters.
Like other Mirion external probes, also the GMP-25 is a ” smart” probe, having an internal high voltage generator and non-volatile memory for calibration coefficients and probe identification data. Thus the probe can be connected “on-the-fly” without the need for switching off the meter, which automati- cally recognizes the probe type and sets the meter reading to defined measuring unit.
