OMB 500UNI
OMB 500UNI
UNIVERSAL BARGRAPH - 50 LED
The OMB 200/300/500UNI model series are simple bargraphs designed for maximum efficiency and user comfort while maintaining their low cost.
The OMB 500UNI type is a multifunction instrument with the option of configuration for 5 different types of inputs easily configurable in the instrument menu.
The instrument is based on a single-chip microcontroller with A/D converter, which secures good accuracy, stability and easy operation of the instrument.
By selecting the mode of insertion of the front plexiglass (reverse/face) you may choose the required printing of scale for vertical or horizontal design of the instrument.
