What is a key difference between the NT2000 and the Ionic generator?

The key difference between the NT2000 and the ionic generator is that the ionic generator incorporates enhanced safety features. This differentiates it as a more advanced option, focusing on minimizing risks during operation. Enhanced safety features may include better electrical insulation, advanced monitoring systems for fault detection, or automated shut-off mechanisms that protect both the equipment and the user. Such improvements are critical, especially in environments where precision and safety are paramount.

Considering the context of the other options, they may suggest aspects about battery life, flexibility, or suitability for specific procedures, but none address the significant aspect of safety in the same direct manner. Therefore, emphasizing the safety features of the ionic generator highlights its advancements and priorities in design and functionality compared to the NT2000.
