Reflex vs Transparent

  • Reflex – The level of the media in the vessel appears black and the prismatic glass reflects silver where the liquid is not present. Light is only required in the front of the gauge.
  • Transparent –  For direct visual observation of the vessel’s liquid, level, quality, and color. Light is recommended from the back or inside the vessel.
