Laboratory Pressure Standards

Laboratory pressure standards sit at the top of a pressure calibration hierarchy, providing the reference against which working calibrators are checked.

Yokogawa and Condec cover this range. These instruments prioritise long-term stability and low uncertainty over portability, and are normally installed in a temperature-controlled laboratory rather than carried to plant. Confirm the accuracy class against the calibrators you intend to verify, since a standard needs a meaningful accuracy ratio over the instruments below it to be useful. Check whether the unit is a piston gauge, a controller or a precision indicator, as these serve different roles in the chain.
