The DH-Budenberg CPB3500 is a compact pneumatic deadweight tester providing superior accuracy and reliability for ranges up to 1600 psi. As a genuine primary standard, it derives pressure measurement directly from the fundamental equation p = F/A, ensuring reliability, stability, and minimal measurement uncertainty .

Built on a stable aluminum base with lightweight impact-resistant ABS case, the CPB3500 is suitable for both laboratory and on-site use. Piston cylinders are interchangeable among various models, allowing easy upgrades when requirements change. Mass sets are fully interchangeable between pistons of the same range and are made of non-magnetic stainless steel for long-term stability .

Two built-in precision soft-seat valves combined with a volume adjuster provide fine pressure control capability. A safety pattern gauge shows approximate pressure. Masses are top-loading for faster operation and are available in common pressure units. Complete with comprehensive accessories and traceable calibration certificate .
