1.1 General Description
The Model 6000-528 External Ion Chamber is a low profile ion chamber designed to measure diagnostic
x-rays from 30 to 150 kVp. The external ion chamber consists of an ionization chamber and a 15-foot
cable assembly.
1.2 Application
The Model 6000-528 External Ion Chamber is specifically designed to be used with the NERO® 6000B,
6000M, 4000+, or the 4000M+ for measuring exposure from diagnostic x-ray machines. It can also be
