Micafluid Converter Station Density Monitors

Micafluid Converter Station Density Monitors

Nov 12, 2003In North America the electricity is only 60hz. That low frequency is why people get strained eyes from fluorescant lights like they have in offices and schools. If we had our power running at a higher frequency like 120hz, we wouldn't get eye strain as much from that type of lighting. It's sort...
