Overview

The WPC-1050 is a general purpose low-background counting system, which is widely used for both health physics and radiochemistry applications. The WPC-1050 is an improved design of the previous WPC-9550 that incorporates the same dependable mechanical platform with improvements which include:

A built-in color touch screen interface
Ability to export data directly to a computer using the PIC Link option
Ability to program routines and QC charts on a PC running the included DUO Express software, then transfer the routines to the instrument using a direct-connect PIC Link cable
Optional gas flow conservation mode available

Part Number: 105-1050
