digitalpiston typeprecision

• Precision better than 3 ppm • Stability better than 3 ppm per year • 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. 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. Instrument base The instrument base is designed with functionality, economy and space conservation in mind. All electronic components are housed away from the instrument base to eliminate errors caused by thermal effects and magnetic fields. The thermally isolated motor drive is connected to the cylinder— eliminating pressure fluctuations and maximizing productivity. A durable, acrylic bell jar is provided to allow absolute and vacuum modes of operation.
