Ludlum Model 2100-1

  Radiation Sample Counter

The Ludlum Model 2100-1 manually operated radiation sample counting system processes sample steel slugs to determine whether any radioactive impurities exist.  The gamma radiation counting system is a table-mounted, fully integrated design that includes a gamma detector, sample tray, and controller. The counting electronics incorporates two channels to distinguish between low and high energy gamma isotopes.  All parameters, such as alarm point and count time are user-adjustable from the front panel LCD touch screen via a simple menu selection. Measurement results for each sample are displayed on the backlit LCD.  An Ethernet port reports all results and system status in real time for remote data logging and alarm annunciation.  Visual and audible alarms are annunciated via the system’s LCD and rear panel mounted buzzer respectively.  A built-in relay provides a method for driving an external horn/strobe (available as an option).  Ludlum also offers an optional Ethernet-based Model 272E remote display for conveniently displaying of one or more sample counters. One rear panel mounted USB port enables connection to either a keyboard or barcode reader device for the purpose of entering sample ID’s.
