microR Meters

These instruments are used for seeking radioactive sources.  They are oftentimes used to locate sources within a load that initiated an alarm while passing through a gateway monitoring system. Ludlum offers several models to suit the budegetary, sensitivity, and physical attributes most are seeking for in this type of instrument.
