2465A Gas Piston Gauge

The Fluke Model 2465 Gas Piston Gauge (formerly Ruska 2465) has a long history of serving national standards laboratories, commercial industry and government organizations as a primary pressure standard for over 40 years. Since its original introduction, enhancements have been made to increase performance and reduce operator workload.

The Model 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.

General
Pressure range	Gauge mode: 1.4 kPa to 7 MPa (0.2 to 1000 psi) gauge Absolute mode: 1.4 kPa to 7 MPa (0.2 to 1000 psi) Vacuum mode: -100 to 0 kPa (-14.5 to 0 psi) gauge (Vacuum pressure achieved depends on local barometric pressure)
Electrical power	115/230 VAC, 50/60 Hz, 15 W
Temperature	Operating temperature 15 to 28?C (60 to 82?F) Storage temperature -20 to 70?C (-4 to 158?F)
Humidity	Operating humidity 20?75% relative humidity, noncondensing; storage humidity 0?90%
Pressure medium	High purity nitrogen or dry, clean air with less than 0.5 ppm hydrocarbon and less than 5 ppm H2O content, dew point less than or equal to -50 ?C, and less than 50 micron particulate size. Although lower quality gas can be used, the frequency of piston/cylinder cleaning will increase.
