Alpha 1 Tricolor Bargraph System


ALPHA 1 TRI-COLOR BARGRAPH SYSTEMS. The ultimate in tri-color bargraph technology. New Alpha 1 Tri-Color Bargraph System uses color as never before…to organize, communicate, and coordinate with clarity.


General Features

  • Made to Order option on physical size or performance specifications means that you can design your own instrumentation control panel or retrofit obsolete "non-supportable" existing meters.
  • Brighter colors, larger LEDs designed for easier reading across the room and from extreme side angles.
  • Superior alarm/ annunciation capability. Four independent alarm systems with complete annunciation flexibility -- flashing setpoints, flashing readouts, flashing bargraphs (color of choice), color intensity control, and reverse video capability.
  • Set-up controls are pushbutton or computer via serial communication port with on-screen prompts for each parameter in set-up sequence.
  • Expanded scale capability (bargraph only). A smal portion or the input can be "zoomed" in on and expanded over the entire bargraph.
  • Three Year Warranty
