RBRquartz³ BPR|zero
The RBRquartz³ BPR|zero is a special version of the robust RBRquartz³ BPR implementing an internal quartz barometer and switching valve. The novel AzeroA technique is used to provide in-situ reference measurements to correct for long term drift in the Paroscientific Digiquartz® pressure gauge. Configured with one or two Digiquartz® pressure gauges, an internal barometer is used in conjunction with a hydraulic manifold to periodically make reference measurements of internal housing pressure. This instrument is intended for deep water, long-term deployments where high stability and resolution of absolute pressure measurements are critical.
