Fluke Ruska 2465


The Ruska 2465 provides the capability of generating pressures to within a total expanded uncertainty of 10 parts per million to 700 kPa (100 psi) and 26 parts per million to 7 MPa (1000 psi). The Model 2465 is available in a variety of configurations to meet individual requirements. The three basic components of the Model 2465 are the Instrument Base, one or more Piston/ Cylinder Assemblies, and a single Mass Set. The Ruska 2465 is capable of operating in gauge, absolute and vacuum mode.


  • Pressure ranges from 1.4kPa to 7 MPa (0.2 to 1000 psi)
  • Accuracy to 0.0010% (10 ppm) of reading for pressures to 700 kPa (100 psi)
  • Accuracy to 0.0027% (27 ppm) of reading for pressures greater than 700 kPa to 7 MPa (100 psi to 1000 psi)
  • Precision better than 3 ppm
  • Stability better than 3 ppm
  • Resolution 0.0001% (1 ppm) or 1 mg
  • Gauge, absolute, vacuum and low pressure modes

The Model 2465 Gas Piston Gauge has a long history of serving national standards laboratories, commercial industry and government organizations as a primary pressure standard for over 45 years.  Since its original introduction, enhancements have been made to increase performance and reduce operator workload.
