Description
The WIKA CPB3500 is a pneumatic dead-weight tester: a primary pressure standard that generates pressure directly from mass and piston area (p = F/A). Five interchangeable piston-cylinder systems cover vacuum to 1 bar, 0.1–7, 0.2–25, 1–70 and 1–120 bar (or psi/kPa equivalents) with an accuracy of 0.015% of reading, or down to 0.006% in the premium version with UKAS certificates.
Two precision valves and a volume adjuster set each point, the mass sets are non-magnetic stainless steel, and the aluminium base with ABS cover is robust enough for site work as well as the laboratory.
