The Fuji Electric PHU is a paperless recorder that features from 9- to 36-channels displayed on a brilliant 12" TFT color LCD, a wide variety of display modes to allow users to view data as trends (horizontally or vertically), bar graphs, analog meters, digital/numeric output, totalized output, event summaries, and more. The PHU allows users to record up to 12 types of thermocouples, 5 types of RTDs, and DC voltage/current input on one unit.
