External pressure adaptor

The external pressure adaptor is designed for the RBRquartz³ instruments and can be used to verify or recalibrate the Paroscientific Digiquartz® pressure sensor.

RBR provides the RBRquartz³ pressure adaptor kit with each instrument. It is not included in the RBR support kit and needs to be ordered separately. You can choose to receive this separate kit at the same time as the instrument, or to request it separately at a later date.

RBRquartz³ pressure adaptor kit includes:

  • pressure adaptor

  • four socket head cap screws

  • 3mm and 5m hex keys

  • five replacement O-rings
