Model GSM-500-MR MicroR Meter with External Probe

The GSM-500-MR MicroR Meter is the external version of the our GSM-501 MicroR Meter. The external plastic scintillation probe is tissue equivalent and measures at the micro R level. The plastic scintillation detector absorbs dose at comparable rate to that of human tissue. Other noteworthy features include auto-ranging, integration, and peak hold. Both gamma and higher energy beta radiation are detectable.  Standard items provided with each system include survey meter, probe, cable, batteries, operations and maintenance manual, and calibration certificate. The GSM-500-MR Micro R Survey Meter is recommended for nuclear power plant, health physics, and medical applications, or whenever dose measurement at the micro R level is required. This micro R survey meter is ideal for NORM measurement. Other applications include oil refineries and scrap metal facilities. Oil refineries often prefer the external probe for measuring inside of pipes and other hard-to-reach areas.
