GSM-500 Four Range Microprocessor Survey Meter
 

The GSM-500 microprocessor survey meter is auto-ranging and features integration and peak-hold operating modes. This survey meter has the capability of simultaneous calibration for counts per minute and dose. Up to two probes can be used for one calibration. Compatible probes include pancake G-M probes, end-window G-M probes, sodium iodide probes, plastic scintillation probes, alpha scintillation probes and others. This quality survey meter offers more features than any other survey meter of its kind at a low price.

• Full Auto-Ranging, Integration & Peak Hold Operating Modes
• Simultaneous Calibration: CPM and Dose.
• Auto Dose Linearization of each probe (based on Cs137 Cal.)
• Alarming option also available
