Model GSM-500-GL  Survey Meter

Auto-Ranging Survey Meter with Low Energy Sodium Iodide Probe

The GSM-500-GL is system that utilizes a four range microprocessor survey and a low energy Sodium Iodide probe. Standard features include auto-ranging, integration, peak hold, instant zero, and linearization of dose response from low energy NaI probe. CPM and dose is selectable via a front panel switch. This survey meter is useful for Iodine-125, Cesium-137 and X-ray detection. Standard items provided with each system include survey meter, probe, cable, batteries, operations and maintenance manual, & calibration certificate.
