Reference primary standards
Pressure balances are high-precision fundamental pressure standards that define the derived unit of pressure directly from the fundamental units of mass, length and time following the formula p = F/A.

The model CPD8000 digital pressure balance is a worldwide exclusivity combining two high-level technologies:

  • High-end piston-cylinder systems, whose effective area (A) converts the pressure into the respective force.
  • High-accuracy force cell which measures the force F.

CPD8000 is defined as a digital pressure balance and is thus a high-precision pressure measurement standard.

The CPD8000 measuring concept is a primary principle. It combines the measurement uncertainty and reliability of fundamental pressure standards with the ease of use of automatic digital pressure measuring instruments.

Easy to use
The model CPD8000 offers the same high measurement uncertainty as a high-end pressure primary standard with the benefits of:

  • Mass load not necessary
  • Built-in reference mass for auto calibration
  • Displaying and digital transmission of fully corrected reference pressure
