Graphtec GL820 20 Channel Data Logger

Graphtec GL820 data logger has built in 125 VAC RMS / 350 VDC isolation on all the analog channels, for a few reasons. First, it means you can hook up your Graphtec GL820 midi LOGGER without the normal worry about ground loops, providing you more flexibility and control. Second, it just makes good technical sense to isolate the inputs, and is even a nice safety feature. Few products in this class provide this kind of isolation as standard…or even as an option!

With its dedicated USB port for flash drives, the Graphtec GL820 makes it easy to transfer data on to your PC or laptop for direct processing.
