A by-product of its highly successful"HI-Q" Series of Programmable Intelligent Controllers and Bargraphs. The "MEGA" Series are medium and giant bar-digital displays that give you trend and present representation of your process. The Automatic Tricolor LED Bargraph (an OTEK innovation) changes color upon reaching programmable set point(s), either a portion of the bargraph, the complete section, or just the pointer. In addition, you can make the display blink or dim via simple serial commands or pre-configure them with OTEK's Navigator (G.U.I.).
