Request Information
The Ashcroft® 1305DH portable deadweight testers are primary pressure standards that include a pressure source for generating precise calibration points. The unit’s built-in shuttle valve provides the means to control the rate of pressure increase, while precision adjustment is accomplished with an integral micro vernier displacement valve. An ideal, rugged field-ready primary standard, the 1305s are certified to yield consistent and accurate results.
