Our Wide Angle Optics Illuminate Boiler Water Level at Any Angle, Any Distance

Installed worldwide since 1962, Simpliport® Boiler Water Level Glass Gages provide reliable direct-reading, bi-color indication up to 3000 PSI (206 Bar).  Continuous advancements to the Simpliport design have made them easier to install, easier to maintain and now, much easier to view.

Wherever you may be standing within 180° of the Simpliport Wide Angle Hood, you can clearly see the bright red or green indication of steam and water level.  You will decrease your exposure time to the boiler environment, while maintaining a crystal clear view of a direct reading gage as required by ASME.
