OMB 412UNI

UNIVERSAL BARGRAPH - 24 LED with Display

The OMB 412 model series are panel programmable three-color bargraphs with auxiliary display, designed for maximum efficiency and user comfort while maintaining their favourable price.
The OMB 412UNI type is a multifunction instrument with the possibility of configuration for 8 various input options, easily configurable in the instrument menu.
The instrument is based on a single-chip microcontroller with a multichannel 24-bit sigma-delta converter, which secures high accuracy, stability and easy operation of the instrument.
