CPB3500 from WIKA

The CPB3500 pressure balance is an excellent standard for measuring pressure because it uses the fundamental formula p = F/A directly. This mechanical measuring principle provides high reliability and stability over a long period of time, minimizes the possibility of measurement errors and reduces uncertainty in calibration. As a result, the CPB3500 is an indispensable tool for daily calibration of any kind of pressure measuring equipment.

Technical specifications

The total measurement uncertainty ranges from 0.015% to 0.006%
Interchangeable pistons and mass sets available
Aluminum base with an impact-resistant ABS cover
Five different piston-cylinder systems


The CPB3500 is a primary standard for calibrating pressure gauges in the range of -1 to 120 bar (-14.5 to 1,600 lb/in²). It is widely used as a reference instrument in plant and calibration laboratories for testing, adjusting and calibrating pressure measuring instruments. The system is completely free-standing and can also be used on-site.
