RBRquartz³ BPR | zero
The RBRquartz³ BPR | zero is a special version of the robust RBRquartz³ BPR (Bottom Pressure Recorder) with an 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 RBRquartz³ BPR | 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 RBRquartz³ BPR | zero are:
-
AzeroA drift correction
-
High accuracy
-
Quartz stability
-
Long deployments
Extend deployment times even further using 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. See RBR Cable Guide for options.
The RBRquartz³ BPR | zero may include an optional built-in tilt sensor (accelerometer).
