OMB 451UNI

OMB 451 is a programmable tri-colour panel bargraph with an auxiliary LED display and a programmable LCD scale. The instrument is based on a single chip microcontroller and a fast 24bit A/D convertor with 8 possible configurations easily adjustable in the instrument’s menu.
Thanks to its dimensions, this instrument is an ideal replacement for the ZEPAKOMP instrument series.
