GSM-115-GL Scintillation Survey Meter for Low Energy Gamma
System includes GSM-115 survey meter and GLE-1 Low Energy Scintillation Probe

This four range survey meter and low energy scintillation probe is ideal for low energy gamma response from 15 keV to 200 keV. This low cost system is analog and manual ranging, but features quality microprocessor electronics. The GSM-115-GL is recommended for  Iodine-125 detection.  The system is housed with rugged aluminum with magnetic shielding. The BNC coaxial connector is useful for quick field replacement. Standard items provided with each system include survey meter, probe, cable, batteries, operations and maintenance manual, and calibration certificate
