Model 4600 Series

Multi-Detector Benchtop Counter

Features

1 to 12 Channels
PC Program Control & Logging
Wide Range High Voltage
Single Channel Analysis
User-Adjustable Parameters

The Model 4600 Series are SCAs (single channel analyzers), ranging from 1 to 12 channels, with PC control of all necessary operating parameters. Each connected detector has independent high voltage, threshold or sensitivity, 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.

Model 4600 Series instruments are supplied with IBM-compatible application software that enables setting up each channel, running counts, and storing the data.
