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, the 1305D is carefully calibrated and certified traceable to the National Institute of Standards and Technology (NIST).
 
The Ashcroft 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.
