Static Holders

  • Static holder for 225 mm sensors
  • Enables quick and easy installation of pH/ORP, conductivity, or dissolved oxygen sensors in process applications
  • Use in new applications as well as for direct retrofit of existing sensors
  • When used in combination with our sensors and cables, the CSS225 will reduce maintenance and replacement
