Type 1305D Deadweight Tester APPLICATION • For calibration and test applications requiring a primary standard FEATURES • Accuracy: 0.1% of reading • Operating Pressure: 15 psi to 10,000 psi • Operating Media: - 1305D: SAE 20 weight automotive or machine oil - 1305DH: Phosphate-based or glycol fluids The Ashcroft 1305D Deadweight Tester is an affordable, portable primary pressure standard, specifically designed for the precise calibration of industrial service gauges and transducers. Accurate to 0.1% of reading, each deadweight tester is carefully calibrated and certified traceable to the National Institute of Standards and Technology (NIST). The 1305D is a “dual-range” system which provides a “high” and a “low” pressure piston assembly and a complete set of weights labeled with corresponding high and low pressure values. Each system includes a “2 speed” lever action hydraulic pressure pump capable of achieving pressures up to 10,000 psi. By repositioning a shuttle valve, the operator can select between 2 different rates of pressure generation, thereby reducing the effort necessary to develop higher pressures. To “fine tune” the pressure output to a specific calibration point, the pump is equipped with a secondary micro-adjust vernier displacement valve. The standard 1305D pump is designed to operate with 20 weight petroleum based motor or machine oil. For applications requiring the use of glycol or phosphate ester based “hydraulic” fluids, the pump is optionally available with special seals suitable for these media. In addition, each set includes the tools, adapters and accessories necessary to accommodate most field or lab calibration requirements. All of the components are conveniently stored in a metal “tool box” for maximum protection and portability. Weight sets are also protected in separate metal storage boxes. The 1305D offers a rugged field ready primary standard, certified to yield consistent, accurate results. All specifications are subject to change without notice.
