Ludlum Model 4612

   Radiation Benchtop Counter

●  12 Channel Benchtop Counter

●  Single Channel Analyzer
●  PC Program Control and Logging
●  Wide Range High Voltage
●  User Adjustable Parameters

The Ludlum Model 4612 is a 12-detector radiation single channel analyzer (SCA) with PC control of all necessary operating parameters. Up to 12 detectors may be connected to the instrument each with independent high voltage, threshold or sensitivity, and window settings. This equipment is supplied with IBM-compatible application software that enables setting up each channel, running counts and storing the data.

SOFTWARE: Provided computer software package allows for setting and changing of all parameters including HV, Threshold, Window, Scaler Count Time, and Output Time. There is also a HV Plateau Routine that allows for detector plateauing of any or all channels of the instrument. Other features include data logging capabilities, and scaler operations in slave or recycle modes. The Model 4612 is a 12 detector Single Channel Analyzer (SCA) with PC control for all necessary operating parameters. Up to 12 detectors may be connected to the instrument; each with independent high voltage, threshold, and window settings. Parameters are loaded from a built-in flash memory during the power up sequence. These parameters include high voltage, upper level discriminator, lower level discriminator, count time, count time range, output time, recycle mode or slave mode.
