1 RBRquartz³ BPR | zero
The RBRquartz3BPR | zero is a special version of the robust RBRquartz³ BPR (Bottom Pressure Recorder) with the
additional advantage of the AzeroA correction technique.
The instrument integrates one or two Paroscientific Digiquartz® pressure gauges, an internal quartz barometer, and a
switching valve. It is the switching valve that provides in situ reference measurements to correct for the long term drift
in the pressure gauge. The resulting drift is several hundred times lower than with uncompensated measurements.
The RBRquartz3BPR | zero is intended for deep, long-term deployments where high stability and resolution of absolute
pressure measurements are critical. Its applications include detection of natural disasters, such as avalanches,
earthquakes, severe weather, tsunamis, and wake turbulence.
Key features of the RBRquartz3BPR | zero are:
AzeroA drift correction
High accuracy
Quartz stability
Long deployments
Extend deployment times even furtherusing external power supply from the RBRfermata (power) or the RBRcervata
(power and memory) canisters. Alternatively, use an extension cable to connect the instrument to an observatory for
external power and realtime data access.
The RBRquartz3BPR | zero may include an optional built-in tilt sensor (accelerometer).
