METEO-LCD-IND · Digital indicatorMETEO-LCD-IND Digital indicator

This indicator is extremely versatile and flexible. The high contrast display can be adjusted by a dimmer to the prevailing lighting conditions. The compact design proves to be very advantageous and cost efficient when mounted into control panels. The instruments are reliable and cross-linkable. They can, when series connected, display all 6 measured main parameters at the same time.

  • Big, graphic, high-resolution display with background illumination
  • Contrast and brightness adjustable
  • Variety with waterproof front plate design
  • Low mounting depth
  • Galvanically separated supply and signal channels
  • Momentary, mean and extreme values
