Ametek Type T [T-5] Hydraulic Deadweight Tester, Single Column, Single Piston/Cylinder, 10 to 500 psi; 5 psi Increments, ±0.100 Of Reading Accuracy w/Standard Gravity Calibration, Water/Alcohol mix (Standard) & Buna-N (Standard). The Ametek Type T Hydraulic Pressure Pump may be ordered with either oil or a water/alcohol mixture as the pressure medium. There are three available seal packages for the system: Buna-N, Viton, and EPT. It features a dual pressure output manifold, fine adjustment vernier valve, relief valve, and dual volume control for rapid pressure increase at lower pressures and easier pumping at higher pressures. Ready-to-use pressure systems for the DPC-500, APC, CPC, and IPI calibrators. For all pressure systems the pump and the indicator are separate systems. Therefore a replacement of the pump does not mean that you have to send the complete system for repair. Maintenance of the instrument is also made easy. Recalibration of the unit can be performed locally with an accurate pressure reference: No need to send the unit back to the manufacturer for recalibration. If you do require a factory calibration, the pump and indicator are independent and only the indicator needs to be returned. JOFRA pressure calibrators are as standard delivered as individual indicators or as a complete calibration systems ready to use in a carrying case, including pump, hose, set of fittings, batteries, test leads, user manual, and a NIST traceable calibration certificate.
