GSM-500 Four Range Microprocessor Survey Meter W.B. Johnson  GSM-500 Auto Ranging Survey Meter CE mark
 Johnson Nuclear GSM-500 Auto Ranging 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.
