• Choice of Materials: Select from aluminum, brass or stainless steel to meet system and media compatibility requirements.
  • Unrestricted Mounting: Allows for horizontal, vertical or inverted installation. Superior Exterior Design Weather-tight for use outdoors and/or on systems where wash downs are required.
  • Rugged and Reliable: These monitors are constructed with all metal pressure vessels, allowing safe, permanent installation in industrial systems.
  • Multiple Ports Available: Standard selection of NPT, SAE and BSPP ports reduces the amount of adapters required for installation.
