The 90M9-AG and 90M9 are invasive sensors.
The mAs sensor connects to models Accu-Gold / Rapid-Gold / Accu-Pro / Accu-kV and to the X-ray generator with safety-shrouded banana jacks. The jacks are not polarity sensitive. It is intended to be inserted in series with the X-ray generator return.
The Accu-Pro and Accu-kV require a kV sensor in-beam as a trigger source.
The 90M9-AG and 90M9 measure DC current. When measuring AC current, we recommend using Model 90M9-BR. Click on the “Sensors and Accessories” tab above for details
